These cells are made of semi-conductive materials, most often silicon, a material that can conduct electricity while maintaining the electrical ialance needed to create an electric field. When sunlight hits the semiconductor in the solar PV cell (step 1 in our high level review) the energy from the light, in the form of photons, is absorbed, knocking loose a nuer of electrons, which then
