Abstract

Gap layer film (GLF) is a thin film material that can improve light utilization and enhance the output power of photovoltaic modules. Some photovoltaic glass products with white glaze reflectors are available on the market, but these products often suffer from compromised glass performance, poor durability, and low light utilization efficiency. Meanwhile, the theoretical basis and optimization schemes for the output power improvement of photovoltaic modules using existing film materials are absent. Here, a GLF based on the structure with a triangular cross-section was designed using simulation methods, and the optimal triangular structure was selected through optical path analysis. Subsequently, the designed GLF was successfully fabricated using nanoimprint lithography combined with an ultraviolet curing process. The experimental results show that the structure improves the short-circuit current and maximum output power of the photovoltaic module by 1.34 % and 1.79 %, respectively. This study presents an efficient and practical solution to enhance light absorption and output power in solar cell modules, providing valuable insights for the future development and application of high-efficiency solar cell technologies.

通过隙层膜提高太阳能电池组件的光吸收效率

间隙层薄膜（GLF）是一种可以提高光利用率和提高光伏组件输出功率的薄膜材料。市场上有一些采用白釉反射镜的光伏玻璃产品，但这些产品往往存在玻璃性能不佳、耐用性差、光利用效率低等问题。同时，利用现有薄膜材料提高光伏组件输出功率的理论依据和优化方案缺乏。本文采用仿真方法设计了一种基于三角形截面结构的GLF，并通过光路分析选择了最优三角形结构。随后，采用纳米压印与紫外固化相结合的方法成功制备了所设计的GLF。实验结果表明，该结构使光伏组件的短路电流和最大输出功率分别提高了1.34%和1.79%。本研究为提高太阳能电池组件的光吸收和输出功率提供了一种高效实用的解决方案，为未来高效太阳能电池技术的发展和应用提供了有价值的见解。
