4 Frequently Asked Questions about “What happens when sunlight shines on photovoltaic panels - Williamson Battery Technologies”

What happens when light shines on a photovoltaic cell?

When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.

What happens when sunlight hits a solar panel?

When sunlight hits a solar panel, it's not just providing warmth and light; it's carrying packets of energy called photons. These photons are the key players in the solar power game. As they strike the surface of a solar panel, they set off a remarkable chain reaction that ultimately leads to the flow of electricity.

What is the photovoltaic effect?

The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It 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.
