A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.

Wafer Slicing: The ingots are then sliced into thin wafers, the base for the solar cells. Doping Process: The wafers undergo doping to form the p-n junctions, crucial for converting sunlight into electricity. Applying Anti-Reflective Coating: This step involves applying a coating to the wafers to increase light absorption and reduce losses. ...

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 …
These pairs create a flow of current that follows the built-in potential slope of the material.
