[0002] The photoelectricity photo-thermal assembly is a kind of assembly that converts light energy into electric energy and heat energy simultaneously, and the solar cell assembly in it carries out photoelectric conversion by the "photovoltaic effect" of semiconductor, and the utilization rate of solar energy is low in this process, and most of the energy is converted into heat energy, and the photoelectricity photo-thermal assembly collects excess heat through heat exchange pipe plate, which can reduce the temperature of solar cell assembly to improve photoelectric conversion efficiency on the one hand, and also can collect heat and supply heat to the outside world.

[0003] However, in the current photoelectricity photo-thermal assembly manufacturing process, the main manufacturing process adopted is: (1) the solar cell assembly is bonded with the metal heat absorption pipe plate by using heat-conducting silicone, but this method has the problem that the bonding between the metal heat absorption plate and the solar cell assembly cannot be maintained stable for a long time due to the difference in the thermal expansion coefficient of the materials, which leads to the photoelectricity and photo-thermal performance of the photoelectricity photo-thermal assembly manufactured by this process to be easily attenuated or even failed, so there are problems of short service life and poor stability, and the process of bonding heat-conducting glue is quite different from the laminating process of the current photovoltaic assembly production, so the current bonding process by heat-conducting glue generally adopts manual glue coating to complete the bonding, so the production efficiency of this process is relatively low, and the stability of the product is also not high; (2) the solar cell assembly is integrally laminated with a flat heat-absorbing metal plate, but due to the difference in the thermal expansion coefficient between the solar cell assembly and the photo-thermal module, the solar cell assembly will be deformed after high-temperature lamination and cooling to room temperature, which affects the quality of the manufactured photoelectricity photo-thermal assembly.
