| Junction diodes are of many types and solar cells are one such. Its working is based on production of potential difference by sunlight. In other words, it is a junction diode that can convert light energy into electrical energy. In such a junction one of them either P or N is made thin so that energy is not absorbed much before reaching the junction. The thin region in such a junction is called emitter and the other region is called the base. These cells are used for charging storage batteries in day time. These are also used in artificial satellites. Its main use is for generating electrical energy in cooking food. |
