Problems solved by technology

[0007] The present invention aims to solve the above problems, and provides a one-time molding lightweight PVT assembly and a preparation method thereof. The PVT assembly uses the heat collecting layer as the supporting body, and compared with the PVT assembly of the prior art, the mass is reduced by more than 50%. It overcomes the problem that conventional PVT in the form of photovoltaic modules-heat collectors is difficult to form in one time; the preparation method of PVT components provided by the invention optimizes the one-time forming process, simplifies the production process, and reduces production costs

Abstract

The invention relates to a PVT (photovoltaic-solar-thermal) technical field, and specifically relates to a one-step molded light-duty PVT assembly and a preparation method therefor. The PVT assembly sequentially comprises a front protection layer, a photovoltaic cell string layer, an isolation layer and a thermal collection layer. Bonding layers are respectively disposed between two adjacent layers, and all layers of the PVT assembly are stacked and then the exterior of the stacked layers is provided with an edge sealing strip. The preparation method comprises the following steps: series welding- type setting-laying-laminating-wiring box installation-edge sealing. The PVT assembly takes the thermal collection layer as a support main body. Compared with a PVT assembly in the prior art, thePVT assembly reduces the weight by 50% or more, and solves a problem that a conventional PVT one-step molding of a photovoltaic assembly-thermal collection plate is difficult. The method provided by the invention optimizes the one-step molding technology, and reduces the production cost while simplifying the production process.

Description

technical field [0001] The invention relates to the technical field of photovoltaic photothermal integration (PVT), in particular to a one-time molding lightweight PVT component and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of the solar heating and power generation market, a large number of industrial and commercial roofs have been occupied, and it has gradually entered the homes of residential users. However, the roofs and balconies of residential users are limited, so it is difficult to arrange solar heating and power generation space at the same time. Therefore, how to make good use of the limited roof area and develop related PVT systems is an important direction to further develop the household market and enhance market competitiveness. [0003] Universities, research institutes and photovoltaic solar thermal manufacturers have carried out a lot of research and development work on PVT systems, and the d...
