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

Abstract

The invention aims to provide a solar through-tube photoelectric conversion device. A through-tube transparent material is sampled; solar photoelectric conversion materials are arranged on inner and outer surfaces of a through-tube device; the solar energy is converted into electric energy; and an opening end is sealed for direct use without packaging, so that the cost of the conventional photoelectric conversion material is reduced. Meanwhile, fluid or a heat pipe is arranged inside a cavity of a through-tube transparent device so as to control the temperature of the photoelectric conversion material. Therefore, high-efficiency conversion efficiency of the photoelectric conversion material is always kept, and the heat energy is transferred through the fluid or the heat pipe for comprehensive utilization. Therefore, the comprehensive integrated utilization of solar power generation, temperature control, improvement of solar conversion efficiency and solar heat utilization is realized.
