Photovoltaic solar cells
Directly convert sunlight into electricity, are made of semi conducting materials.
Calculators
Types:
Crystalline Silicon- most popular
Thin film - Thin film photovoltaic cells use layers of semiconductor materials only a few micrometers thick, attached to an inexpensive backing such as glass, flexible plastic, or stainless steel. Cost less than the Crystalline Silicon
