Solar Power Through Photovoltaic Cells

Some pv cells can convert artificial light into electricity.

Solar power through photovoltaic cells.

This phenomenon was first exploited in 1954 by scientists at bell laboratories who created a working solar cell made from silicon that generated an electric current when exposed to sunlight. Solar pv cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. Photovoltaic cells convert sunlight into electricity a photovoltaic pv cell commonly called a solar cell is a nonmechanical device that converts sunlight directly into electricity. When light shines on a photovoltaic pv cell it may be reflected absorbed or pass right through it.

It is a form of photoelectric cell defined as a device whose electrical characteristics such as current voltage or resistance vary when exposed to light. Solar cells also called photovoltaic cells convert sunlight directly into electricity. How much electrical current we get out of the solar cell compared to the optical power put in. Photovoltaics often shortened as pv gets its name from the process of converting light photons to electricity voltage which is called the photovoltaic effect.

That makes it uniquely capable of converting light into electricity. Photons carry solar energy. The pv cell is composed of semiconductor material which combines some properties of metals and some properties of insulators. Individual solar cell devices are often the.

There are many photovoltaic cells within a single solar panel and the current created by all of the cells together adds up to enough electricity to help power your home.
