- Lecture Date: Tuesday, January 24, 2012. One of the greatest challenges humanity faces is finding a way to provide the world's population with clean energy. Since sunlight is our most abundant source of energy, solar cells, which absorb sunlight and create electricity, will become increasingly important over the next several decades. There have been great advances recently using silicon and thin films of semiconductors to make solar cells and solar electricity is just starting to become economically competitive. It is still important, however, to drop the costs further so that it will be possible to utilize even more solar energy. After providing an overview of the solar cell technologies that are currently commercially available, Professor McGehee will describe a relatively new approach that could make it possible to print solar cells in roll-to-roll coating machines similar to those used to make newspapers. Professor McGehee will show how solar cells can be made with organic semiconductors and explain how these cells work. Lecturer: Michael McGehee, Stanford University.
I have 2 cats in my family one a Black cat (Oil) and the other a Red cat (Solar). They are litter mates. Yet... the Black cat is almost twice as big. When I put food pellets on the floor (spread around in an area), Black covers as much as possible with his body and eats the morsels in front of him as fast as possible at risk of indigestion. Red goes about daintily eating the morsels around the perimeter and outside of his reach. If Red gets too close to Black the ears go up and the claws come out.
This is a true story and I witness it every morning... I fudged a bit on the "Oil and Solar"...that is not the cat's real names and I am sorry if I offended them... 'cause the level of greed exhibited by the real Oil is much more offensive than our little Black critter.

Good Lecture, I liked it.
Thanks millions for your lecture
Many thanks for your good video
great lecture.
Great lecture, I like it
awesome!
thanks
ok audio kicks in after 3:20
I found a detailed and accurate project on the Avasva website.
It's great.3Q.
