WebPhotocell. A photocell is a technological application of the photoelectric effect.A photocell consists of a semi-cylindrical photo-sensitive metal plate C (emitter) and a wire loop A (collector) supported in an evacuated glass or quartz bulb. It is connected to the external circuit having a high-tension battery B and microammeter ( μ A). WebPhotocells Definition. Photocells are also known as photoelectric cells which work on the principle of photoelectric effect and converts light energy into electric energy. Overview of Photocells. Photo electricity is firstly explained in 1905. The principle says that the beam of light consists of various energy packets known as photons.
