A community portal about Solar cells with blogs, videos, and photos. According to Wikipedia.org: A solar cell is a device that converts photons from the sun into electricity. In general, a solar cell that includes both solar and nonsolar sources of light is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.
