Embodiment 1

[0038] Photovoltaic curtain walls are integrated into buildings, also known as Building Integrated Photovoltaics (BIPV). In the existing BIPV buildings, most of the photovoltaic curtain walls are of five-layer laminated structure, and the photovoltaic curtain wall of the five-layer laminated structure is not good in terms of heat insulation and sound insulation; in addition, there is also a hollow photovoltaic curtain wall, so Although the above-mentioned hollow photovoltaic curtain wall has good heat insulation and sound insulation performance, it does not have a good infrared barrier effect, so the indoor and outdoor environments can still exchange heat through thermal radiation, which is not conducive to achieving the purpose of energy saving and heat preservation.

[0039] Based on this, the present invention provides a kind of photovoltaic curtain wall, with reference to figure 1 , the photovoltaic curtain wall includes: a double glass assembly and a laminated glass 4; th...

Embodiment 2

[0049] The present invention also provides a method for making a photovoltaic curtain wall, referring to Figure 4 , the method specifically includes the following steps:

[0050] Step S1: making a double glass assembly through a lamination process, the double glass assembly including top glass and bottom glass.

[0051] This step may further include steps S11-S15, specifically as follows:

[0052] Step S11: providing top glass.

[0053] The top glass is the first layer of glass for making double glass components. After the photovoltaic curtain wall is installed on the building, the top glass is the glass seen from the outside, and it can also be called the front of the photovoltaic curtain wall. Glass.

[0054] Step S12: Laying a first sealant on the top glass.

[0055] Step S13: laying solar battery sheets on the first sealant.

[0056] In this step, a solar cell layer is laid on the first sealant, and solar cell layers of different shapes or patterns can be laid accord...

Abstract

The embodiment of the invention discloses a photovoltaic curtain wall and a manufacturing method thereof. The photovoltaic curtain wall comprises a double-glass assembly and sheet lamination glass, wherein the double-glass assembly and the sheet lamination glass are separated by utilizing a separating bar to form a hollow layer; the double-glass assembly comprises top surface glass and bottom surface glass; and at least one of the double-glass assembly and the sheet lamination glass is low-radiation glass. In the photovoltaic curtain wall provided by the embodiment of the invention, because at least one of the double-glass assembly and the sheet lamination glass is arranged as the low-radiation glass and the low-radiation glass has higher reflectivity on an infrared ray, the photovoltaic curtain wall has the functions of high thermal insulation and low radiation, and indoor and outdoor heat exchange generated by thermal radiation can be effectively reduced so as to achieve the purposes of energy saving and thermal insulation.

Description

technical field [0001] The invention relates to the technical field of the photovoltaic industry, and more specifically relates to a photovoltaic curtain wall and a manufacturing method thereof. Background technique [0002] At present, building energy consumption accounts for about 30% of the total energy consumption of the society, and air-conditioning energy consumption accounts for 40-50% of building energy consumption. Therefore, improving the thermal insulation performance of photovoltaic curtain walls on buildings has become an important issue for energy conservation and emission reduction. [0003] The structure of the known photovoltaic curtain wall is a five-layer laminated structure: glass-encapsulant-photovoltaic cell-encapsulant-glass. After the five-layer laminated structure is formed, the photovoltaic curtain wall is formed through processes such as packaging and assembling junction boxes. The structure of the photovoltaic curtain wall is a double-glass lamina...
