Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. Below, you can find resources and information on the. . Solar cell When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. They are composed of numerous solar cells made of semiconductor materials, typically silicon, which capture solar energy and convert it into usable electricity. Solar energy is the cleanest and most abundant renewable energy source available, and the U. Photon-electron interaction, 3.
