Problems solved by technology

[0004] At present, universities, research institutions and photovoltaic manufacturers have carried out a lot of research and development work on PVT systems, and the difficulties in product development are mainly concentrated in the combination of photovoltaic power generation components and solar thermal collector panels, photovoltaic power generation functions and solar thermal heat collection. Function, the two functions use different corresponding materials, if the two functional components are simply superimposed, they are not integrated into an integrated structural design, there are big problems in actual production, the reliability of the product is poor, and the industrialization of the manufacturing industry cannot be formed Scale and benefit

[0005] Patent authorization announcement number CN213367725U and patent publication number CN 112532177 A, the patent application publication date is March 19, 2021, authorized and announced "a high-efficiency heat-collecting photovoltaic module", the light-receiving surface material of the photovoltaic panel is made of transparent The cover plate material is transparent PET or fluororesin film, which is different from the glass used on the light-receiving surface of conventional photovoltaic modules. Obviously, the patented technology above cannot meet the requirements of 20 years in terms of safety and reliability such as flame retardancy, UV protection, and hail resistance. and above service life, cannot meet the 25-year / 30-year quality assurance requirements of photovoltaic industry components; "a high-efficiency heat-collecting photovoltaic module" authorized and announced above, its photovoltaic function board is directly attached to the heat-collecting substrate, such a collection For the thermal substrate, due to the process requirements of direct lamination, the bonding surface of the heat collecting substrate needs to be flat, and because the inside of the heat collecting substrate needs a raised flow channel, which makes the other layer of the heat collecting substrate cannot be flat. The layer panel is asymmetrical, and after the finished product is manufactured by double-layer sealing welding, the entire heat-collecting substrate is greatly deformed, and the cells are fragmented and cracked after being bonded to the photovoltaic function board, which affects the power generation function and service life of the photovoltaic cells

Therefore, the above patented technology is not a mature industrial product application technology, and needs to be changed and innovated in design
