Problems solved by technology

[0007] 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 energy photovoltaic device of a vacuum glass tube. Solar energy optical to electrical material is arranged and processed in the vacuum layer of the vacuum glass tube to convert solar energy into electric energy; after the vacuum glass tube is sealed, the vacuum glass tube can be directly used and does not need to be packaged so as to lower the cost of the existing optical to electrical material; meanwhile, fluid or a heat pipe can be arranged in the cavity of a vacuum glass tube transmitting device to control the temperature of the solar energy optical to electrical material, so that the solar energy optical to electrical material can always keep high-efficiency conversion effect, and heat energy is comprehensively utilized after being transferred by the fluid or the heat pipe, and thus, solar energy generation and temperature control are realized, solar energy conversion efficiency is improved, and solar energy heat is comprehensively and integrally utilized. In order to improve solar energy utilization efficiency, a solar energy mirror is arranged out of the device to focus solar energy, i.e. reflect, refract, project solar energy, and in order to reduce heat waste, an insulating layer is added out of the device.
