One of the courses I took in my senior year was a semiconductors course. There was one topic I was really interested in and that was solar cells. I will just go over a little bit of what I learned/remember from class.
A solar cell is a semiconductor device that uses the suns radiation to produce electrical energy. Typically a solar cell is a p-n junction diode. This means that the solar cell is a combination of an n-type semiconductor and p-type semiconductor material. The reason why is because the p-n junctions potential energy barriers are...
