This video puts the complexity of solar energy and solar cells into plain English.
Associate Professor of Materials Science and Engineering Jeff Grossman explains photovoltaics/solar cells.

When they start taxing the Sun (and they will do that), FIGHT BACK ! DO NOT PAY A SINGLE $
Amazingly done ! A helpful video indeed..
A simple and didactical way to explain how solar cells work! Thanks :)
good job thanks sir
Great video!!!!1
The most effective solar panels, although great, are only capturing less than a tenth of what they could be attaining from basking in the sun's output of the EM spectrum. Even if photovoltaic cells could absorb 99.9% of the electromagnetic energy they're bathing in, it would be a small dispersed fraction of the sun's energy. This is because the cell is covering a speck of the suns 129,600 degrees of directional output; I'm no math wiz, so someone correct me if I'm wrong, but the sun is roughly a sphere and a circle is 360 degrees so add the third dimension and 360X360 be the directional coverage of a sphere right? I think 3D objects use a different mathematic media to describe what I'm talking about, but I haven't learnt such math yet, or didn't understand it if I have, but I digress.
About that directional output I was referring to, if you start to draw 360 lines from a point using a protractor you'll see that the space between the lines becomes greater as the lines get further out. This can give you a numeric understanding as to why the suns radiation becomes less dense or concentrated as you get further out without being a physicist. In conclusion, if you want to get the most energy out of the sun you'd need to get as close to it as possible and build something like a Dyson Sphere. However, this would far exceed our power needs.
can u tell me ,why only solar light is used to generate the power.i mean why the light coming from household bulb is not used
no really infinite, but last for millions of years
Yah we know the oil company doesnt own the sun, no one does
can you tell me, what aplikasi you use to make this video. especially at the house part.
sorry because my english is bad.
excellent explanation
lost me at "infinite" lol
please do a video about how does an inverter work
Excellent! Would you allow me to translate it into Portuguese? If so, please adjust the settings to enable translations. Anyway, thanks for sharing.
1000 kW/hour per m^2 or 1000W/hour per m^2?
Nice piece of work ….. and you mostly kept the muzac under control .
nice job! easy explanation
Thank you for making it simple and understanding
Thank you very much sir for sharing this valuable video..
2:20
Phosphorus? Did you mean silicon in that bit?
thanks for the information
nice presentation. Hope we make the transition from FF to solar soon.
people come on the You Tube for visual effect of solar cell not for watching your face…
So that explains why solar is advancing so slowly
Storage USED to be a problem..
Thanks, Elon!
