Problems solved by technology

[0004] The first is that the solar cell sheet in the photovoltaic module is in an arc-shaped position, which is prone to cracks and debris during the lamination process, resulting in a low yield of photovoltaic modules and relatively high production costs;
[0005] The second is that the solar cells inside the photovoltaic module are on a curved surface, and the solar cells are connected in series. When the sun shines, due to the different radiation received by different solar cells, the The mismatch between them is

Abstract

The invention belongs to the technical field of solar battery products, and particularly discloses a multi-plane double glazing photovoltaic module and a preparation technology thereof. The photovoltaic module comprises front cover glass, a first PVB film, a plurality of battery stings, a second PVB film, rear cover glass and two junction boxes, wherein the rear cover glass and the front cover glass are completely accordant in shape and bent inwards to form a multi-plane glass pane structure with a plurality of planes, the solar battery stings are correspondingly positioned at the planes of the glass pane structure, solar battery pieces arranged on the same plane are connected in series to form a battery sting, and the battery stings on different planes are connected in parallel in the junction boxes. According to the multi-plane double glazing photovoltaic module, the deficiency that in a laminating process, the solar battery pieces are easy to create debris due to keeping in a bent state is overcome; mismatching probability of the photovoltaic module is reduced; rate of finished products is greatly improved; and service life of the photovoltaic module is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation products, and in particular relates to a multi-faceted double-glass photovoltaic module and a preparation process thereof. Background technique [0002] In the prior art, arc-shaped double-layer glass is usually used to make curved BIPV photovoltaic modules (Building Integrated PV is Building Integrated Photovoltaic), and two pieces of ultra-white tempered glass with exactly the same arc are used to make the arc-shaped ultra-clear tempered glass After the glass, PVB film, battery string, PVB film, and arc-shaped ultra-clear tempered glass are laminated, they are placed in an autoclave for lamination. [0003] The curved double-glass photovoltaic module produced by the above process has many shortcomings, which are mainly manifested in the following two aspects: [0004] The first is that the solar cell sheet in the photovoltaic module is in an arc-shaped position, which is p...
