It is also called photovoltaic or PV cells. These cells are used to convert sunlight into direct electricity and are grouped together to make solar panels. Photo/light+voltage = photovoltaic.
Solar cells are used to converter sunlight into direct electricity. Sunlight strikes the surface of these cells which absorb photons and release elections. These electrons are captured and make it energy. Solar cells are grouped together to form the solar panels that are placed on your roof when you go solar.
