Flat-plate water-heating photovoltaic/thermal module and production process thereof

A process for producing flat-plate water-heating photovoltaic/thermal module comprising a frame having a lower surface that is is provided with a heat preservation back plate and an upper surface that is sequentially laminated with a glass cover plate, a first photovoltaic cell laminating adhesive, a photovoltaic cell slice, a second photovoltaic cell laminating adhesive, a transparent back plate, a third photovoltaic cell laminating adhesive and a heat absorbing component from top to bottom, a heat preservation cavity being formed between the heat preservation back plate and the heat absorbing component, the process comprising:

• sequentially placing the transparent back plate, the second photovoltaic cell laminating adhesive, the photovoltaic cell slice, the first photovoltaic cell laminating adhesive, and the glass cover plate from bottom to top;
• performing a first lamination step to prepare a pre-module, the first lamination step comprising laminating the sequentially placed transparent back plate, second photovoltaic cell laminating adhesive, photovoltaic cell slice, first photovoltaic cell laminating adhesive, and glass cover plate;
• manufacturing a heat absorbing component that comprises a heat absorbing metal plate and a cooling pipeline composed of metal small pipes and metal headers that are welded to the lower surface of the heat absorbing metal plate;
• embedding the cooling pipeline of the heat absorbing component into a laminating mold;
• sequentially stacking the third photovoltaic cell laminating adhesive and the pre-module on an upper surface of the heat absorbing component to form a lamination of the laminating mold, the heat absorbing component, the third photovoltaic cell laminating adhesive and the pre-module, wherein the transparent back plate of the pre-module is attached to the third photovoltaic cell laminating adhesive and wherein the transparent back plate is a double-sided modified transparent TPT and the first photovoltaic cell laminating adhesive, the second photovoltaic cell laminating adhesive and the third photovoltaic cell laminating adhesive are all POE adhesive film;
• and
• performing a second lamination step to form an integrated laminating structure, the second lamination step comprising laminating the lamination of the laminating mold, the heat absorbing component, the third photovoltaic cell laminating adhesive and the pre-module.
