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 ...
