NOVELTY - Packaging of building integrated photovoltaic (BIPV) module involves (a) cleaning and blow-drying a photovoltaic cover, (b) using laser additive manufacturing technology to prepare a layer of silicon oxide with a certain thickness in the circumferential direction of the photovoltaic cover, (c) covering a polyvinyl butyral (PVB) film on the photovoltaic cover processed in the step (b), and then combining with the photovoltaic module to obtain a module, and then laminating and packaging the module, and (d) using galvanometer laser welding machine to weld the interface between the silicon oxide layer and the photovoltaic module. The thickness of the silicon oxide layer is 50-200 microm more than the thickness of the PVB film. USE - Packaging of building integrated photovoltaic (BIPV) module used in construction industry. ADVANTAGE - The method is economical, and enables packaging of building integrated photovoltaic module packaging in short period of time, and is capable of increasing the sealing performance of the photovoltaic module, reaching the effect of sealing water, so as to meet the BIPV industry to the fire-resistant requirement of the photo-electric power generation, and expand the application prospect. The photovoltaic module has excellent effect and durability. The thickness of the silicon oxide layer can be optimized according to the actual shrinkage of the PVB film.
