PV Cells 101: A Primer on the Solar Photovoltaic Cell
How a Solar Cell Works. Solar cells contain a material that conducts electricity only when energy is provided—by sunlight, in this case. This material is called a semiconductor; the "semi" means its electrical conductivity is less than that of a metal but more than an insulator''s. When the semiconductor is exposed to sunlight, it ...
