What does Photovoltaic stand for?

Photovoltaic, also known as PV, refers to the use of light to generate electricity. In most cases, this light source is the sun.

The word "photovoltaic" comes from two ancient Greek words, "photo", which means light, and "voltaic", which means something to do with electricity.

So literally, photovoltaic means "photoelectric".

The photovoltaic effect is created using thin sheets of conductive materials such as silicon. When photons hit the material, electrons are excited. Direct current is generated. In this way, you can get electricity from sunlight.
