[0002] When climate anomaly becomes a global consensus, carbon neutrality becomes the only way to solve the climate crisis. In the foreseeable future, new clean energies such as wind energy, solar energy, water energy, and nuclear energy will replace traditional fossil energies with serious pollution such as oil, coal, and natural gas and become the mainstream energies of countries around the world. Photovoltaic power generation has inexhaustible solar energy resources, and the solar photovoltaic power generation technology using photovoltaic modules composed of solar cells has developed rapidly. According to different terminal requirements, photovoltaic power generation systems can generally be divided into distributed photovoltaic power generation systems and centralized photovoltaic power generation systems. A distributed photovoltaic power generation system is a photovoltaic power generation facility built near a user's roof or idle site, where the user uses the power generated by themselves and sells the excess power to the grid. A centralized photovoltaic power generation system, on the other hand, uses sites with rich sunlight resources such as deserts and gobi to centrally build large-scale photovoltaic power generation facilities, and basically all the generated power is sold to the grid. Based on the rich building roof resources in China and the advantages of controllable investment costs and simple construction processes of distributed photovoltaics compared with centralized photovoltaics, the market potential for building rooftop distributed photovoltaics in China is huge.

Therefore, the photovoltaic module cannot receive all the solar energy, and its power generation efficiency is not very high. Therefore, a device for improving the power generation of a distributed photovoltaic double-sided double-glass module is proposed to solve the above problems. Content of the Utility Model
