HOW Solar Works
How a PV cell makes electricity
Under the sun, a photovoltaic cell acts as a photosensitive diode that instantaneously converts light (but not heat) into electricity.
NOTE: PV system
>> A photovoltaic system (informally, PV system) is an arrangement of components designed to supply usable electric power for a variety of purposes, using the Sun (or, less commonly, other light sources) as the power source. Solar PV total global capacity increased during 2010-2013 from 40 GW to 139 GW.
