Problems solved by technology

However, since the outer glass of the hollow photovoltaic module is composed of photovoltaic modules, the photovoltaic module will generate a lot of heat during the power generation process. The heat cannot be discharged due to the hollow layer of the hollow photovoltaic module, and the accumulation of heat will cause th...

Embodiment Construction

[0027] Such as figure 1 , 2 , 3, 4, 5, and 6, the present invention is a breathing type hollow BIPV photovoltaic module, including front glass 10, solar battery sheet group 11, substrate glass 12, hollow layer 17 and back glass 13 stacked in sequence, wherein A spacer 15 is installed between the substrate glass 12 and the back glass 13 so as to form the hollow layer 17, a sealant 16 is used for air sealing between the substrate glass 12 and the back glass 13 outside the spacer 15, and the front glass 10 A junction box 14 is installed between the back glass 13 and electrically connected to the junction terminals of the aforementioned solar cell array 11 .

[0028] The front glass 10 is made of low-iron ultra-clear tempered glass, and the substrate glass 12 is made of low-emissivity glass that only reflects infrared light with a wavelength above 1100nm. The low-emission glass is formed by covering the tempered glass with an infrared reflective film. In addition, a desiccant is...

Abstract

The invention relates to a photovoltaic building integral solar photovoltaic assembly, in particular to a breathing type hollow BIPV (building integrated photovoltaics) assembly. The breathing type hollow BIPV assembly comprises front glass (10), a solar cell group (11), base plate glass (12), a hollow layer (17) and back glass (13), wherein the front glass (10), the solar cell group (11), the base plate glass (12), the hollow layer (17) and the back glass (13) are sequentially stacked, a spacing strip (15) is arranged between the base plate glass (12) and the back glass (13) to form the hollow layer (17), the gap between the base plate glass (12) and the back glass (13), outside the spacing strip (15), is subjected to air sealing by a sealant (16), a terminal box (14) is arranged between the front glass (10) and the back glass (13), and the terminal box (14) is electrically connected with a wiring terminal of the solar cell group (11). The breathing type hollow BIPV assembly solves the problem of the hollow photovoltaic assembly that the glass is crushed due to overhigh pressure of the glass hollow layer in the power generation process in summer.

Description

technical field [0001] The invention relates to a photovoltaic building integrated solar photovoltaic module, in particular to a breathable hollow BIPV photovoltaic module. Background technique [0002] There are two main types of BIPV (Building Integrated Photovoltaic) battery components in domestic and foreign industries: one is ordinary dual-wave battery components, and the other is hollow photovoltaic components. [0003] Ordinary dual-wave battery modules are also called the first generation of BIPV battery modules, which use tempered glass instead of the back protection material of photovoltaic modules and are packaged with adhesive film. This kind of BIPV battery module has undoubtedly broken the technical barriers of the photovoltaic industry and the construction industry, but there are also many drawbacks that directly restrict the development of BIPV battery modules. The first is heat insulation ability: energy transfer is nothing more than three kinds of radiatio...
