Concentrator photovoltaics is a technology that uses concentrating technology to replace expensive solar cells with relatively inexpensive concentrators, and concentrates sunlight on the surface of the solar cells to generate electricity.
First, due to the high efficiency of photoelectric conversion, CPV technology is the most ideal solar power generation technology that can be used to build large-scale supporting power supply.
Second, compared with crystalline silicon and thin-film solar power generation technology, CPV has no advantage in the construction cost of 3-4 US dollars / WP at present, but with the expansion of production scale, the improvement of battery efficiency and the improvement of concentrator module, the cost will be greatly reduced, and the potential advantage is great.
Thirdly, the CPV concentrator photovoltaics power plant covers a small area under the same power generation, and the change of shadow area does not affect the ground ecology due to the change of the inclination angle of the tracking system.
Fourth, the CPV concentrator photovoltaics system almost does not consume water in the power generation process, only a small amount of water is needed to clean the glass shell of photovoltaic modules, which has obvious advantages of water saving.
In addition, there are many advantages that will not be described. Why is the most advantageous technology not widely used? Because the current technology is not mature, there are still many problems to be solved, such as how to improve the material to further improve the light resistance of photovoltaic cells, how to solve the problems of uneven illumination and low efficiency under high concentration, In addition, the uneven light intensity will lead to uneven heating on the surface of the battery, so the requirements for materials are also very high, as well as the research and development of radiator performance. Because of these advantages and problems, CPV system (concentrator photovoltaics) can not really play its high efficiency, but it gives us a lot of space for exploration and research. Therefore, CPV (concentrator photovoltaics) has a huge development prospect.
