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

A flat-plate water-heating photovoltaic/thermal module, comprising a frame, wherein

• the lower surface of the frame is provided with a heat preservation back plate;
• the upper surface of the frame 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, 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
• a heat preservation cavity is formed between the heat preservation back plate and the heat absorbing component.
