Problems solved by technology

The application of existing photovoltaic modules in BIPV often has many disadvantages. For example, the power generation efficiency of photovoltaic modules is greatly affected by the light transmittance. At the same time, the control effect of the modules on temperature and light is not good, and the problems of air bubbles and sealing have also become problems that affect the power generation of the modules. Therefore, the service life of photovoltaic modules is easily affected. In addition, BIPV has high requirements on the fire resistance of photovoltaic modules, and the application of existing photovoltaic modules is limited to a certain extent.

Embodiment

[0032] This embodiment relates to a packaging process for BIPV photovoltaic modules using laser additive manufacturing technology, which specifically includes the following steps:

[0033] a: Use ultrasonic waves, roller brushes or high-pressure water spray to clean the photovoltaic cover, and then use a hot air knife to dry the cleaned photovoltaic cover; the photovoltaic cover can be selected from ultra-white tempered glass, soda-lime glass, borosilicate Glass or stainless steel sheet;

[0034] b: Laser additive manufacturing technology is used to prepare a layer of silicon oxide layer with a certain thickness in the circumferential direction of the photovoltaic cover plate; the thickness of the silicon oxide layer is optimized according to the thickness of the PVB film covered behind, and it is required to be 50-200 μm thicker than the thickness of the PVB film , the thickness needs to be optimized according to the actual shrinkage of PVB; the main component of the silicon ...

Abstract

The invention relates to a BIPV photovoltaic module packaging process applying a laser additive manufacturing technology. The process comprises the following steps of: preparing a silicon oxide layer in the circumferential direction of a photovoltaic cover plate by using a laser additive manufacturing technology, covering the photovoltaic cover plate with a PVB film, performing combination and lamination packaging with a photovoltaic module, and finally welding an interface between the silicon oxide layer and the photovoltaic module by using a laser galvanometer to obtain the BIPV photovoltaic module. According to the packaging process, the sealing performance of the photovoltaic module can be improved, the fireproof requirement of the BIPV industry for the photovoltaic module is met, and the application prospect is expanded.

Description

technical field [0001] The invention relates to the technical field of production of BIPV photovoltaic modules, in particular to a packaging process of BIPV photovoltaic modules using laser additive manufacturing technology. Background technique [0002] As a green and clean energy, solar energy has gradually been widely used with the enhancement of social environmental protection awareness. Building Integrated Photovoltaic, or BIPV for short, is a technology that integrates solar power (photovoltaic) products into buildings, breaking the barriers between the traditional photovoltaic industry and the construction industry. The application of existing photovoltaic modules in BIPV often has many disadvantages. For example, the power generation efficiency of photovoltaic modules is greatly affected by the light transmittance. At the same time, the control effect of the modules on temperature and light is not good, and the problems of air bubbles and sealing have also become pro...
