Solar Power Through Photovoltaic Cells

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 power through photovoltaic cells.

Individual solar cell devices are often the. 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 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.

Solar cells also called photovoltaic cells convert sunlight directly into electricity. Testing solar cells is usually done to figure out one or more of the following. 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. 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.

The pv cell is composed of semiconductor material which combines some properties of metals and some properties of insulators. How much electrical current we get out of the solar cell compared to the optical power put in. That makes it uniquely capable of converting light into electricity. Some pv cells can convert artificial light into electricity.

This is specific to the wavelength or colour of light and is usually plotted as a curve.
