Photovoltaics
When light strikes the cell, electrons are knocked loose from the silicon atoms and flow in a built-in circuit, producing electricity. PV Terminology Solar Cell: The PV cell ... than STC yielding a 10% power drop) would actually produce about 90 Watts. A thin silicon cell, four inches across, can produce more than one watt of direct current (DC) electrical power ...
