Problems solved by technology

[0005] However, due to the photoelectric conversion rate of commercial solar cells in the concentrating photovoltaic power generation technology that people use is generally less than 20%, the remaining more than 80% of the energy is lost in the form of heat energy, and the heat generated makes the concentrating solar cells The performance of solar energy is reduced, which further reduces the utilization rate of solar energy, which greatly limits the further promotion of solar energy applications.
