The Photoelectric Effect and Its Applications to Solar Cells

The photoelectric effect occurs when electrically charged particles are released from or within a material when illuminated by light (or electromagnetic radiation). The light ejects electrons from the surface of the metal, and these electrons can cause an electric current to flow. The phenomenon was discovered in 1887 by the German physicist Heinrich Hertz.
