"Getting Moore from Solar Cells" by David J. Norris and Eray S. Aydil, Science 2012, 238, 625.
After describing some new and interesting materials for solar cells, the authors state:
"Although this sounds exotic, these materials are known to behave like semiconductors, allowing them to absorb the sunlight and create electrons"At the risk of sounding pedantic, electrons are not created--nor are they destroyed. They are there in the dark in the beginning, and they are still there after the lights go out. The electrons are merely excited by the light.
Photons knock up electrons and then leave the seen.
