Solar cell / photovoltaic cell / cell

The solar cell is the smallest element in a solar module. The raw materials are semiconductor materials for the production of the cells, such as silicon, germanium or gallium arsenide, whereby silicon cells are widespread. The sunlight is converted in the cells by the photoelectric effect. With the supply of light in the cells are separated positive and negative charge carriers from each other and electrical field and voltage are developed. A consumer will be attached to relieve this voltage and there flows direct current. So that the developed direct current can be used, inverters must be attached, which convert the direct current into alternating current.
