How to generate solar cells, the principle of PN junction
Solar energy is an inexhaustible renewable energy source for human beings, and it is clean energy and does not produce any environmental pollution. In the effective use of solar energy; solar energy photoelectric utilization is the fastest growing and most dynamic in recent years
The production of solar cells is mainly based on semiconductor materials, its working principle is the use of photoelectric materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into: 1, silicon solar cells;
Salt, such as gallium arsenide III-V compounds, cadmium sulfide, copper indium selenium and other multi-compound materials for the battery; 3, functional polymer materials prepared by the large solar cells; 4, nano-crystal solar cells.
