Basic Definition of Solar Cells

Solar cells are materials that absorb sunlight and convert it into electricity.Today’s photovoltaics industry is a product of 1950s solid-state electronics, and was greatly stimulated by the need to find power sources for America’s place satelites.Its beginnings though, can be traced back to 1839 when scientists observed that light falling on certain material created a difference in electric response(in other words, it created electricity).They further discovered that the amount of electricity produced varied with the amount of light and intensity.This is called the Photovoltaic Effect(photo-for light, and voltaic-for voltage).
