A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junctio. A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p. 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. The inci.
