Solar Power Through Photovoltaic Cells

The pv cell is composed of semiconductor material which combines some properties of metals and some properties of insulators.

Solar power through photovoltaic cells.

Solar pv cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. When light shines on a photovoltaic pv cell it may be reflected absorbed or pass right through it. 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. Photovoltaics often shortened as pv gets its name from the process of converting light photons to electricity voltage which is called the photovoltaic effect.

This is specific to the wavelength or colour of light and is usually plotted as a curve. Solar cells also called photovoltaic cells convert sunlight directly into electricity. A solar cell or photovoltaic cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect which is a physical and chemical phenomenon. Testing solar cells is usually done to figure out one or more of the following.

Some pv cells can convert artificial light into electricity. 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. That makes it uniquely capable of converting light into electricity. Photons carry solar energy.

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.
