I discovered this channel a few years ago while researching for my science fair project, on making my own solar cells. It’s pretty cool to see the new breakthroughs on the things that I researched about, using free articles online.
As someone who works in the solar industry, perovskites are very interesting (as is graphene conductors). Anything that may increase the efficiency of solar panels and their electricity generation is going to be good for the renewable future. I wonder if you’ve ever looked into inverter efficiency because converting DC to usable AC power (and in a safe way) is also a hurdle for solar electricity. Thanks for another great video.
@@thomasbonse why do you have to be so hard on cold fusion. It's trying really hard. Just another 30 years and they might have it. If you don't believe me, ask me again in 30 years and I'll give you the same answer.
@@Mike__B they are making massive steps forwards in relation to graphene, the production costs have been cut drastically and they can now manufacture it in large quantities at decent prices. So now the next step is graphene sheets but graphene in small portions are already being used in the UK in road construction with asphalt and concrete and seems to be showing very impressive results but I suppose it still needs to pass the test of time.
What do you want to look into regarding inverter efficiency? Microinverters are commonly 90% efficient and modern high frequency string inverters that are currently on the market are 95%+ efficient. There's no point in chasing the last 1 or 2% possible of efficiency since it'd likely make products more complicated, expensive, and/or shorter lived.
Love your stuff! So hard to be scientific and still hold the attention of the rest of us. Very informational and interesting. Keep up the good stuff while dummying it down without loosing either us or the information.
2:44 _"They created a perovskite film with a plasmonic substrate made of hyperbolic metamaterial and characterized it with transition dipole orientation."_ Language like that is opaque for most of us. I appreciate this channel demystifying it.
Great episode. I appreciate the breadth of your research, and how you present a topic with integrity rather than trafficking solely in hype and clicks. I mean, you clearly put in the work, and it shows. Cheers!
With over 38 years of advanced material reinforcement and chemical engineering experience, I have done advanced Perovskite application development for solar panels, etc. Perovskite stabilization is key for application longevity performance. Sitting on various ASTM (I) committees over the decades, I have co-authored many testing and measurement standards, which need to be agreed upon for all new technologies. Taking the new technology mentioned into practical applications is my specialty.
Personally, the line was crossed with all the bs they say VPN do. All the ads youtubers bake in are pretty terrible. I give them no credit I just ignore it as them trying to have a career on the site. This channel is just a tech news show.
2FA was huge step forward. There are phishing and hacking methods that completely bypass 2FA. Just look at the Linus Tech Tips hack that just happened a month or two ago. Stealing someone's browser cookies/session data can allow someone right into your account. If the 2FA is using a cellphone number to text you a code, that's also hackable by cloning your cellphone number and receiving the code (it's also happened in the wild). 2FA isn't bulletproof.
I can never be a sleeper agent watching your videos. I always open my eyes and watch what your talking about and miss out on sleep. Your videos are pre bed time after work
LOL was getting ready to bypass your video only because I was thinking exactly what your intro video stated 10-15 years away. It was great to hear you say that was not so.
You really have the best job. I'm sure these videos take a lot of time to research. Good job looking at and researching all of the things in your videos and explaining them to us in a way we can understand.
I'm super excited for this because I'm looking to put solar panels on top of a bus and in that case size matters way more than lifespan because I don't have very much room so having more efficient solar panels even if they don't last quite as long is acceptable especially if they're cheaper
1000 hours to 95%. It's just 4 months (8h/day). Silicon based panels keep that for 10 years and the best ones for 20. So you're still a 30* factor behind. The problem is also the labor to change panels. You have to be really really cheaper if your lifespan is shorter or the cost to do the change more often will absorb that gain.
They didn't have time to test more yet, they only concluded that is still holding 95% in 1000 hours, but they will need months more to check if it can, for instance, reach 10k hours over lets say 90% and so on. Its a new tech, you can't expect them to have it tested for decades even on advanced wear facilities
@@MrCaiobrz You expect linear or less degradation? But it could be even worse. It could snowball and be exponentially bad... Anyway, even with the most optimistic case, it's still an order of magnitude behind silicon. Concerning the advertised value, it's not because they didn't have the time, it's because they want to give a good number that can be easily remembered. 95% and 1000h looks good for the average Joe but it's actually not much.
I think the "diffusion-stability-hysterisis nexus" from their actual paper title sounds like _way_ better Star Trek techno babble than "ionic desire path" 😊
I really appreciate this video. For those of us who don’t live down at or near Boca Chica, we count on those that do to give us the insight to what’s going on & the vibe. We get a lot of launch site or build site videos, but rarely ever get videos covering the village.

Thanks for the comment. Not every advance is going to be a winner, but it's worth keeping an eye on everything that's happening. There's a lot of interesting work out there.
Thank you for your time and intelligence. You lay out the information very good, you don't put your spin on it to sway there view of the facts. I would like to thank you and will pass your page on to others
I’ve been watching you for years. Love how you describe the information your presenting. You took something I really wasn’t interested in and drew me in. Thank you. Sleeper agent activated. 😂 10:03
I miss the old discovery channel shows. But you are filling that void. So I honestly do thank you and ask you to please don’t stop making them. I do ask one thing. Lead, is detrimental to the environment you say. But the environment is what created lead. It’s a organic element on the periodic table. Just don’t eat it. And I use organic from the much older version of the Websters dictionary. Like 1950’s Meaning from the Earth, I truly thank you again and your videos are very educational and factual and I like that.
I could see these used more here in Louisiana. Nothing is expected to survive long here anyways because of hurricanes and even the lead risk isn't a factor because of our abysmal environmental record. I am glad to see there is progress here. I want to have solar eventually and this looks like it is worth the wait.
What I really want (need?) to know is how the economics play out. If we can get better efficiency for less then the payback period improves. Currently in the UK it would take 12-15 years to payback a residential solar installation any improvement on that would make them a lot more attractive to any user.
For the most part, I've enjoyed watching your videos. However, one of the biggest issues with the corporate world is their love of the all mighty dollar. It has slowed down advancements more than anything else.
Solar panels with 22% efficiency at converting light into electricity are NOT efficient. 78 of the sunlight is not converted into electricity The amount of inefficiency is far greater than the efficiency. Ergo, it is inefficient.
@@suryakisku3895 solar panels are actually the cheapest thing in the solar power system. during noon time, I even have to cover the panels to avoid excessive heat and extra power to avoid overcharging my off-grid system. my solar panels are only about $20 per 100 watts.
Thanks! Would be interested in more discussions between you and the technical leads at the various commercial companies to learn more about their upcoming products. Any mention of life time for the stuff coming out in 2023/2024?
You, like many, seem to be obsessed with perovskites. Yes, cheaper is a very good thing, and their efficiency is good too. Lifespan MUST be addressed before they can compete with silicon. Still... my personal favorite PV concept is the rectenna. These seem to have a long lifespan and potential for efficiency that other PV technologies can't even dream about. As with all technologies, the limiting factors are: first, making it work and second, manufacturing. An update on today's state of the art of the rectenna would be nice.
The thing in your video that astonished me is that there is no international standards for measuring performance (if I understood you correctly) - I worked for a year or so at the National Institute for Biological Standards and Controls (NIBSC) in the UK and a major part of their job was agreeing (at the time with the US CDC) on international standards for diseases. They also produced samples of international standard quality diseases and exported them to researchers around the world. The purpose being that if Professor Singh in Bombay was working on a Hepatitis A treatment he could publish his work and it's efficacy could be directly compared with the results achieved by Professor Smith at Harvard, or Schulz at Heidelberg - and be easily replicated by other scientists verifying Singh's research. I mean we've only been looking at PV systems since the 60's - you'd have thought someone could agree on something by now.
We're Off-Grid on 15.3kw and the panels really aren't the issue although the more efficient the better. It's the batteries that need a cleaner, cheaper, and renewable solution.
Efficiency is an issue because that determines the cents per watt. Increasing the efficiency benefits both off grid as well as on grid users. In the off-grid use case it means the total monetary outlay is lower. In the on-grid case, it can make the difference in the economics of whether to install a PV system or not.
Great job following up on the most current technologies for solar production. Hope you continue to update us on the comercial availability of perovskite panels.
Should- might- maybe. I would be delighted when you release a video stating facts relating to real ,scalable, and most importantly commercially avaliable improvements .
“O” boy Matt, finally, you may remember I got you to report on Perovskite years ago. It’s taken long enough. It’s ok, I needed time to learn to say it correctly. Thank you for that. Nice to see you again. How’s the new house ? Now maybe I can soon start designing bldgs with solar in the bldg structure. 👍✌️
Sometimes efficiency is approached from the wrong side. Instead of wasting time to make solar cells more efficient, how about we make the manufacturing and recyclablity more efficient and greener? You know? Perfect first what we have? This has been in R & D already for so long, and what do we have? Silver and lead. More mining and toxicity. Lovely. Bravo...
Thanks for this, Matt. We live on our boat, so we depend on our solar panels, but we need pretty robust ones. These developments are certainly interesting, & I'll be keeping my eye on the industry. But besides needing reliability, I have a lot invested in controllers & such. I get the feeling we're still 10 years out here...
Hi Matt, has there been any information about durability of any of the perovskites? For how many days can they maintain at least 70% of their original efficiency?
Hi Matt, Oxford PV has been announcing commercially available perovskite PV by 2020, then 2021, 2022,… Any chance of a video showing what keeps delaying Oxford PV and commercial manufacturing of perovskite PV over the last 3+ years?
Just some input as to why the liquid process might be difficult to scale. Thin films of liquid are typically applied to a surface through use of a spin coater. They spin at incredibly high speed and so only the liquid close to the surface can actually stay on the wafer. This means that for an 8” wafer it’s not that big of a deal. But a three foot solar panel that’s a ton of centripetal acceleration for the material to cope with.
No no. The production is done with single wafers and dried and then the contacts added and the module assembled. the process just becomes faster when a slot dye coater is used butthe efficiency drops alittle.
The “unbreakable iron triangle” is broken all the time by new technologies because it only is intended to evaluate acquisition options with current technologies.
This content is really very deep...i did 2 courses but i never get this type of content...please also make videos on current research opportunities and on some conpanies...it will help student to grab some opportunity
Excellent excellent excellent video, thank you! I wish there were some funding program to get these five universities/companies to start integrating their research with each other now, in order to optimize rollout later. We're down to the environmental wire here.
I would like to know if this method relates in any way to what Aptera has just done with their new glass solar panels on their soon to be released car.
Another good one Matt, the numbers with efficiency seem to be a bit over the top with respect to 11:48 ? Can't wait for an update on your new house Matt.
Today's science news on YT always feels like the science news of the 1980s, with virtually the exact same topics, because no real progress has been made.
Hmmm. The first 4 advances still look like they're in the research stage, or 5 years away from commercialization (and is often the case, 5 years from now, the prediction will be "5 years away"). Furthermore, each seem to address specific issues with perovskites, but don't look like they can be combined to address all issues. For number 5, Matt addresses the elephant in the room, which is how long before anything shows up on the market. But there is no indication of what compromises these first generation products will be making (performance, cost, toxic production methods, etc.), or whether the target markets will be broad or niche. To progress from research to engineering to mass production is incredibly complex and challenging. It makes you appreciate successes in technology even more.

So heated rollers for powder to panels?
Another very informative video. Love the succinct quality.
Fascinating research and so well explained. Thanks for the really interesting presentation - learnt alot.
Hi Matt, has there been any information about durability of any of the perovskites? For how many days can they maintain at least 70% of their original efficiency?
It's about 3/4 the through the video.
Hi Matt,
Oxford PV has been announcing commercially available perovskite PV by 2020, then 2021, 2022,…
Any chance of a video showing what keeps delaying Oxford PV and commercial manufacturing of perovskite PV over the last 3+ years?
Just some input as to why the liquid process might be difficult to scale. Thin films of liquid are typically applied to a surface through use of a spin coater. They spin at incredibly high speed and so only the liquid close to the surface can actually stay on the wafer. This means that for an 8” wafer it’s not that big of a deal. But a three foot solar panel that’s a ton of centripetal acceleration for the material to cope with.
No no. The production is done with single wafers and dried and then the contacts added and the module assembled. the process just becomes faster when a slot dye coater is used butthe efficiency drops alittle.
The “unbreakable iron triangle” is broken all the time by new technologies because it only is intended to evaluate acquisition options with current technologies.
in the future could you link to the articles or abstracts, plz. Great info thanks!
I hope you'll be visit Intersolar one of renewable energy exhibitions see new designs innovation by the companies on solar.
Very good points!
Keep it up, soon we’ll have the creative solar generator
This content is really very deep...i did 2 courses but i never get this type of content...please also make videos on current research opportunities and on some conpanies...it will help student to grab some opportunity
Excellent excellent excellent video, thank you! I wish there were some funding program to get these five universities/companies to start integrating their research with each other now, in order to optimize rollout later. We're down to the environmental wire here.
We need better, cheaper, smaller solar - I’m so excited to see this progress
Very informative 👍
I would like to know if this method relates in any way to what Aptera has just done with their new glass solar panels on their soon to be released car.
Another good one Matt, the numbers with efficiency seem to be a bit over the top with respect to 11:48 ?
Can't wait for an update on your new house Matt.
Thanks for the video.
Today's science news on YT always feels like the science news of the 1980s, with virtually the exact same topics, because no real progress has been made.
I'm glad to hear they're improving solar cells. Maybe 1 day we can use solar power to travel
Hmmm. The first 4 advances still look like they're in the research stage, or 5 years away from commercialization (and is often the case, 5 years from now, the prediction will be "5 years away"). Furthermore, each seem to address specific issues with perovskites, but don't look like they can be combined to address all issues. For number 5, Matt addresses the elephant in the room, which is how long before anything shows up on the market. But there is no indication of what compromises these first generation products will be making (performance, cost, toxic production methods, etc.), or whether the target markets will be broad or niche. To progress from research to engineering to mass production is incredibly complex and challenging. It makes you appreciate successes in technology even more.
Yes, I think we read the same paper recently. I found it on my news feed.
Sitting on various ASTM (I) committees over the decades, I have co-authored many testing and measurement standards.
Thanks for dropping the knowledge! Are there any public companies that are focusing on using Perovskites? Would love to research and invest.
keeping hope alive, good vid
Would love to see a video on googles new Solar API 🤩 .Total game changer!!
i like the spead up in techno solar, end costefectif,s
