Photvoltacic cell is the most basic unit of the whole system which is used to produce electricty from light enrgy.
this is generally made of silicon aoms which has valency of 4 elctrons aand therfore it shares its 4 elctrons with other earest si atoms and forms covalent bond.
When light strikes the cell some part is reflected some gets transmitts from the materrial and some gets absorbed by thecell.
