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
Solar panels operate on a principle known as the photovoltaic (PV) effect. When sunlight hits a solar cell, it knocks electrons loose from their atoms, generating a flow of electricity. This is achieved through the creation of an electric field, which occurs due to the presence of two different types of silicon within the cell—one that''s
