Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
An experimental and theoretical investigation of thermophotovoltaic (TPV) energy conversion using silicon photovoltaic cells has been performed. These cells are intended for use in a proposed solar-electric system that, in concept, uses concentrating mirrors focused on a TPV converter that operates at high power density and high efficiency.
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.
