Solar battery module for glass curtain wall

Abstract

The invention discloses a solar battery component used for a photoelectric glass curtain wall, which consists of a panel, an intermediate layer, and a substrate, wherein the intermediate layer is a sealed adhesive layer encapsulated with a photoelectric panel; the photoelectric panel comprises a plurality of solar battery sheets arrayed in a matrix; positive and negative electrodes of each adjacent battery sheet are serially connected through welded bands to form a battery sheet string; the positive and negative electrodes of the battery sheet string are led out through corresponding electrode leading welded bands and are correspondingly connected with a junction box; the battery sheet string is also provided with a bypass leading welded band; at least two junction boxes are arranged and are respectively encapsulated with a bypass diode; the junction boxes are serially connected with each other to constitute a junction box string, wherein the positive and negative electrodes are respectively connected with the corresponding electrode leading welded bands; a middle node of the junction box string is connected with the bypass leading welded band to ensure that each bypass diode is reversely connected in parallel to the series circuit of the battery sheet string. The solar battery component of the invention is applicable to manufacturing the photoelectric glass curtain wall; the photoelectric property is good; the installation is easy.

Description

technical field [0001] The invention relates to a device for converting solar energy into electric energy, in particular to a solar cell module used for a photoelectric glass curtain wall. Background technique [0002] A solar cell is a semiconductor device capable of converting light energy of sunlight into electrical energy. Because it does not need water, oil, gas or fuel, it can generate electricity as long as there is light. It can be called a clean, pollution-free renewable energy source and is favored by people. In recent years, the application range of solar energy has become wider and wider. Combining solar cells with glass curtain walls on buildings to make solar cell modules has been practically applied and achieved significant economic benefits. [0003] In the prior art, if attached Figure 1~3 As shown, the solar cell module used for the photoelectric glass curtain wall is mainly composed of the panel 1, the middle layer 2 and the bottom plate 3. plate; the p...

Problems solved by technology

[0004] However, since the three bypass diodes are arranged together in a junction box, the volume of the junction box is relatively large, and because the joint between two adjacent glass pieces is small, the installation space is limited, so in the actual installation process It is often difficult. In addition, in order to facilitate installation and strengthen the strength of the overall glass curtain wall, the two junction boxes of two adjacent solar cell modules are overlapped and installed in the same joint, between the two junction boxes in the center of the glass interference; on the other hand, in the lead-out process, each ribbon needs to be arranged in parallel to the junction box in the middle, and the laying of each ribbon is too concentrated, so that the distance between them is extremely small. image 3 As shown, the distance between the electrode lead-out ribbon 7 and the bypass lead-out ribbon 8 is very small. During the process of glass gluing and sealing, the lead-out ribbon will be bent or shifted, resulting in a change in the distance between the solder ribbons. When the solder ribbon When the spacing is less than 3 mm, the electrical performance of the battery assembly may be reduced during use; and the bent ribbon will also affect the overall appearance of the battery assembly
