As the country pays more and more attention to environmental protection issues, solar modules are widely used in building systems in different forms, such as rooftop power stations and building-integrated photovoltaic curtain walls. In the traditional BIPV curtain wall design scheme, there are various product forms, such as hollow curtain wall components, light-transmitting curtain wall components, etc. Taking the hollow curtain wall component as an example, the hollow curtain wall component formed by combining solar cells with hollow architectural glass is a new application way of solar energy products. It organically combines the photovoltaic power generation system with the building, which can not only meet the requirements of building lighting, aesthetics and functionality, but also make full use of building windows, glass curtain walls and lighting roofs to generate electricity, which has the effect of killing two birds with one stone. However, solar cell modules are semiconductor devices that use sunlight to generate electricity. In order to withstand long-term outdoor exposure to sunlight, rain, wind and sand, hail, rain, snow, acid rain and other environments, effective sealing protection must be carried out, including preventing water and air from entering. Solar battery chips, especially the anti-seepage protection of the positive and negative terminals. However, in the design of these products, the junction box is placed on the edge of the component, and the bonding area of the junction box is relatively small.
