How to do a contact angle measurement (Quickstart guide)
มุมมอง 17K2 ปีที่แล้ว
The contact angle of a droplet on a surface can be determined using a piece of equipment called a contact angle goniometer. This technique is an indirect measurement of surface wetting and can be used for a wide range of scientific applications such as: scaling up thin-film production, solvent/material compatibility, cleaning substrates, and hydrophobic coating. This guide teaches you how to us...
How to do transmission & absorption measurements using an optical spectrometer (Quickstart guide)
มุมมอง 1.4K2 ปีที่แล้ว
A spectrometer takes a light beam and splits it into its various wavelengths - it then measures the relative intensities of each of them. The constituent properties of the sample can then be determined through examination of the wavelength and intensity of light. This guide teaches you how to conduct transmission and absorption measurements using the Ossila Optical Spectrometer. Find out more a...
How to measure the resistivity of a conductive film using a four-point probe (Quickstart Guide)
มุมมอง 10K2 ปีที่แล้ว
A four-point probe is a device that's used to measure the sheet resistance of a material. Sheet resistance is a key property of materials, and is often used in material characterisation and during the development of thin-film devices such as solar cells or OLEDs. This guide teaches you how to measure the sheet resistance of a substrate using the Ossila Four-Point Probe. Find out more about this...
How to perform cyclic voltammetry of a polymer using a potentiostat (Quickstart guide)
มุมมอง 10K2 ปีที่แล้ว
A potentiostat is a type of measurement device used to output potential at a controlled rate. It contains feedback circuitry between the output and measured potential unlike other voltage sources - enabling it to keep a consistent potential throughout a circuit with varying resistance. This guide teaches you how to use the Ossila Potentiostat to carry out cyclic voltammetry of a polymer. Find o...
How to create a thin-film using a vacuum-free spin coater (Quickstart guide)
มุมมอง 13K2 ปีที่แล้ว
Spin coating is often used as the starting point and reference for many thin-film processes, even if they will eventually get mass-produced using printing-based techniques. This guide teaches you how to create high quality thin-films using the Ossila Spin Coater. Find out more about this product: www.ossila.com/products/spin-coater
How to fabricate perovskite solar cells (quickstart guide)
มุมมอง 28K2 ปีที่แล้ว
Perovskite solar cells need several layers to effectively separate and extract charge. This guide will teach you how to fabricate perovskite solar cells successfully in a glove box.

What type of FTO glass you use ?
so much for a starter diy gotta diy some of the process before you can diy a cell
Hi. Can I use this device for proton exchange membranes proton conductivity?
This is very helpful! Thank you!
When you have a material and you want to apply it to glass, how do you work this way?
I want to know what type and name of the solution you added to the substance
Helpful
Thanks for showing the clear procedure for measurement of ionic conductivity. Can it be used in case of thin film of Alkaline polymer electrolyte membrane for ionic conductivity measurement?
Hi, did you use a simple glass slide as your substrate?
Yes you can
We have made nanoparticles in lab. we want to make thin films using spin coater. how do we find out optimal spin speed and duration?
Where can I find the other video if possible??? I am not getting anything on my graph.
Hi, do you get the graph?
No description makes it hard to understand, there is a great market opportunity if you had specified use of sonicator, uv ozone cleaner, furnace for annealing etl ,perovskite composition , antisolvent used ,htl , patterning etc to a newbie
Unfortunately it was not a too understandable video... the part where you make the electrodes, it looks like gold but you didn't specify anything. 😑
Can anyone tell me that for the synthesis of perovskite solar cell first have to fabricate perovskite? Or we can synthesis directly perovskite solar cell ?
I guess people are supposed to guess what you are doing
creating a thin-film using a vacuum-free spin coater what is unclear?
I would like to know that antisolvent is consist of which component at 3:23?
How powerful wil a solar panel be? Watts
4:45 🧐 must be hot...
Great video！
Can you please upload a detailed video on how to use glove box and thermal evaporator properly, thanks
Thanks for the suggestion! What specific challenges are you experiencing with these products?
@@ossila4616 Thanks for your reply! I think many new researchers would like to know that 1. How to insert materials inside the golve box? 2. what are the optimized oxygen, water etc. levels in the glove box for fabricating high PSCs? regarding the thermal evaporator, I would like to know the whole procedure for fabricating the back electrode. If it is convenient, please upload.
You're literally asking for trade secret casually
"We recommend cleaning in IPA" A thousand bearded hipsters nod in agreement.
What happened to the annotations? 😋
Hi Universe Becoming, what annotations were you hoping for?
@@ossila4616 Well, at 0:54 there is an annotation stating that the dip is in acetone, and thereafter there are no more annotations. I'd like to see annotations for every chemical, machine, and process.
@@universebecomingltd All of the chemicals and machines used are mentioned in the closed captions. To toggle them on, press 'c' on your keyboard. They can also be switched on via the control bar at the bottom of the video. Hope this helps!
@@ossila4616 Yes! That helps immensely! Thanks! 😁
@@universebecomingltd No problem - happy to help!
How speed and time do you use, sir? and your precusor have low viscosity or high viscosity? Thank you
Hi Niswatul, in this case we used a speed of 3000rpm for 60 seconds with a low viscosity solvent. If you have any further questions, you can speak to our technical team by visiting: www.ossila.com

I like this. would be nice to see highschool science classes teach students about this sort of stuff
Thanks, Entity - we feel the same way!
