Solar cells, or photovoltaics, are made out of photosensitive semiconductors that convert light energy into electricity in a process known as the photoelectric effect. This process describes the interaction between light energy and the materials that make up the individual cell. Depending on how the cell is configured, conversion efficiencies can exceed 30%!
The solar requirements document can be used by educators to help teach students about solar power. Once completing, the students get a solar badge
