Solar photovoltaics (PVs) are arrays of cells containing a material that converts solar radiation into direct current electricity. Materials presently used for photovoltaics include amorphous silicon, polycrystalline silicon, mircocrystalline silicon, cadmium telluride, and copper indium selenide/sulfide. Due to growing demands for renewable energy sources, the manufacture of solar cells annd photovaoltaic arrys has advanded dramatically in recent years.

At the ASES solar park we have a Solar PV display board that demonstrates the entire process from photons of the sun to electrons in our wall outlets.

Nellis Solar Power Plant at Nellis Air Force Base in the USA. These panels track the sun in one axis.
