摘　　要：光伏电池作为国家"双碳战略"中的重要一环,其转化效率的提升具有重大意义。针对晶硅等太阳能电池的无效转化区域,通过全反射原理,设计、制备了微结构光增强薄膜,薄膜的微结构为周期、槽深都是80μm的三角槽型正交光栅。对贴合薄膜样品的光伏电池组件进行测试的结果表明,三组组件的转化效率都提升了2%以上。相对其他提高光伏电池效率的方法,该方法简易、可行且有效,有望广泛用于光伏电池组件,为国家的"双碳战略"做出贡献。Photovoltaic cells as an important part of the national "dual carbon strategy", the improvement of its conversion efficiency is of great significance. Aiming at the invalid conversion area of crystalline silicon and other solar cells, this paper designs and prepares microstructure light-enhanced films based on the principle of total reflection. The microstructure of the film is triangular groove orthogonal grating with period and groove depth of 80 μm. The test results of photovoltaic cell modules fitted with thin film samples show that the conversion efficiency of the three groups of modules is increased by more than 2%. Compared with other methods to improve the efficiency of photovoltaic cells, this method is simple and feasible, and is expected to be widely used in photovoltaic cell modules, and contribute to our country′s "dual carbon strategy".
