Optical lens for Concentrated Solar
With the increasing demand for energy, the development and efficient utilization of energy has become a major issue in the world today. Solar cells are widely concerned for their clean, flexible and other advantages. Concentrating solar power is one of the types. Here, The editor will introduce the principle of concentrating solar power to let everyone know more about how it works.
Concentrating solar technology magnifies the received solar energy hundreds to thousands of times through lenses or mirrors, and then focuses the magnified energy on small photovoltaic cells with extremely high efficiency. By amplifying solar energy, this technology effectively reduces the amount of semiconductor materials in photovoltaic cells.
CPV condenses light from a certain area in a small area (focal spot) through the concentrating system by concentrating light. The solar cell only needs the size of the focal spot area, which greatly reduces the amount of solar cells. Under the same conditions, the higher the magnification, the smaller the solar cell area required.
1) New cost reduction technology path for photovoltaic power generation.
2) The system conversion efficiency is high. The high-rate CPV adopts Group III-V compound batteries such as GaAs, and the conversion efficiency of the CPV system reaches 28%, which is much higher than that of silicon-based solar cells and thin-film solar cells.
Solar cells are a promising new type of power source, with three major advantages of permanence, cleanliness and flexibility. Solar cells have a long life. As long as the sun exists, solar cells can be invested once and used for a long time; compared with thermal power generation, Solar cells will not cause environmental pollution.
