Solar Cell: Working Principle & Construction (Diagrams Included)
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 electrodes on the top of the p-type semiconductor layer.. These electrodes do not obstruct light to reach the thin p-type layer.
