A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical.
When light photons reach the p-n junctionthrough the thin p-type layer, they supply enough energy to create multiple electron-hole pairs, initiating the conversion process.
A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p-n junction diodes. A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor. We then apply a few finer electrodeson the top.
