Problems solved by technology
[0002] Existing photovoltaic modules include sequentially stacked back sheets, EVA, battery sheets, EVA and glass, which are laminated and bonded together at high temperature by a laminator to form the photovoltaic module. Two layers of EVA materials and one layer of backing are required. Plate and a piece of glass also need to use multiple tin-plated solder strips, the amount of material used is large, and its production cost is high; at the same time, fragments will be further increased during the pressurization process; in addition, due to the There is a layer of melted EVA between them, which reduces the light transmittance of the photovoltaic module to a certain extent, thereby reducing its output power; in addition, EVA is used in the photovoltaic module to bond the cells, backplane and glass into one, making The three cannot be separated from each other, so the scrapped photovoltaic modules are a kind of garbage that cannot be recycled, which reduces the utilization rate of photovoltaic modules
