A solar cell is a device that captures the energy of the sun in the form of direct sunlight and converts it into electrical energy. A solar cell is also known as a photovoltaic cell, which implies that it converts the photons present in the light into a voltage difference (which essentially means "electrical power"). To understand the ...

When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the "semi" means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal. There are several different semiconductor materials used in PV …
In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another. Terrestrial solar cells are measured under AM1.5 …
