The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy.The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.
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.
