Problems solved by technology

[0006] However, in the existing solar photoelectric conversion cells, solar photoelectric conversion materials are processed on a substrate material, and glass and other packaging are added to the outside. At the same time, since there is no further temperature control device, the photovoltaic cells are affected by temperature during use. , the power generation efficiency of the usual battery at noon is actually reduced. If the temperature control device is added, the cost of the solar panel will be increased, and the comprehensive utilization of photovoltaic light and heat will not be realized at the same time. Energy and thermal energy, affecting the comprehensive utilization efficiency of solar energy
