How do solar cells work?

Unfortunately, typical solar cells are only about 15 percent efficient, so we can only capture a fraction of this theoretical energy: perhaps 4–10 watts per square meter. That''s why solar panels need to be so big: the amount of power you can make is obviously directly related to how much area you can afford to cover with cells. A single solar ...

How Thin-film Solar Cells Work

In reality, silicon-wafer cells achieve, on average, 15 to 25 percent efficiency. Thin-film solar cells are finally becoming competitive. The efficiency of CdTe solar cells has reached just more than 15 percent, and CIGS solar cells have reached 20 percent efficiency. There are health concerns with the use of cadmium in thin-film solar cells.
