1. A process for producing a flat-plate water-heating photovoltaic/thermal module, the process comprising the following steps:
S1: manufacturing a pre-module: sequentially placing a transparent back plate, a second photovoltaic cell laminating adhesive, a photovoltaic cell slice, a first photovoltaic cell laminating adhesive and a glass cover plate from bottom to top, and placing the resulting system into a laminating machine for a first laminating, to prepare the pre-module;
S2: manufacturing a heat absorbing component, and embedding a cooling pipeline of the heat absorbing component into a laminating mold; and
S3: sequentially stacking a 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 placing the lamination into a laminating machine for a second laminating to form an integrated laminating structure;
wherein the flat-plate water-heating photovoltaic/thermal module comprises a frame;
wherein a lower surface of the frame is provided with a heat preservation back plate;
wherein an upper surface of the frame is sequentially laminated with the glass cover plate, the first photovoltaic cell laminating adhesive, the photovoltaic cell slice, the second photovoltaic cell laminating adhesive, the transparent back plate, the third photovoltaic cell laminating adhesive and the heat absorbing component from top to bottom;
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;
wherein a heat preservation cavity is formed between the heat preservation back plate and the heat absorbing component; and
wherein the heat absorbing component comprises a heat absorbing metal plate and the cooling pipeline, which is composed of metal small pipes and metal headers is welded to a lower surface of the heat absorbing metal plate.
