6003 Anodized aluminum sheet for solar cells

May 03, 2023

The back plate of the solar cell has the characteristics of improving the power generation efficiency of the battery, simple structure, and convenient manufacturing. The technical solution is: 6003 Anodized aluminum sheet for solar cells, characterized in that the backsheet includes 6003 Anodized aluminum sheet , the two surfaces of the aluminum substrate are respectively a fluorine film layer, and an oxide layer is between the aluminum substrate and the fluorine film layer . The thickness of the substrate is 0.15mm-0.50mm. The thickness of the fluorine film layer is 0.02 mm to 0.10 mm. The thickness of the oxide layer is 3 μm-5 μm.



Since the 6003 Anodized aluminum sheet is used as the substrate, the heat dissipation performance is ficantly enhanced, so the overall temperature rise of the solar cell module is much lower than that of the conventional PET substrate back film encapsulated module, thereby greatly improving the photoelectric conversion efficiency (about 15% -30%) 0 Moreover, the oxide film itself ensures the electrical insulation performance of the aluminum plate, on the other hand, it also enhances the anti-aging performance of the substrate, thereby ficantly prolonging the service life of the component. In addition, since the structure is simple and the manufacture is very convenient, the cost is also low.
