The flow of electricity results from the characteristics of the semiconductors and is powered entirely by light striking the cell. Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. As the details evolve, two cornerstones have emerged. On this page you'll find resources to learn what solar energy is; how you, your business, or your community can go solar; and find resources for every step of the way. Solar. . Solar cell When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load. You can join them to illuminate the future of energy.
