What is a Solar Cell?Solar Cell DefinitionA solar cell (also known as a photovoltaic cell) is an electrical device that transforms light energy directly into electrical energy using the photovoltaic effect.Working PrincipleThe working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.Construction DetailsSolar cells consist of a thin p-type semiconductor layer atop a thicker n-type laye
