Abstract

The preparation of high-performance passivating interlayer materials with low-cost strategies is critically important for the development of silicon solar cells. Herein, a PSS/silver nanowire composite film (AgNWs–PSS) was synthesized by a solution-based method, which possesses superior electrical conductivity and passivation performance simultaneously. The conductivity of the film was optimized through the process of annealing, which resulted in a sheet resistance of approximately 40 Ω/□. At the optimal concentration (1 wt %), the minority carrier lifetime on the silicon surface was increased by approximately 3.3 times. The study shows that by adjusting the rotation speed to optimize film thickness and uniformity, the average photovoltaic conversion efficiency of the optimized devices reached 12.42 ± 1.1% (with a maximum efficiency of 13.5% for a single cell). In addition, efficiency improvements of at least 5% were observed at other concentrations.

AgNWs-PSS作为硅太阳电池局部纳米线传导的钝化中间层材料

低成本制备高性能钝化中间层材料对硅太阳能电池的发展至关重要。本文采用溶液法合成了具有优异导电性和钝化性能的PSS/银纳米线复合膜（AgNWs-PSS）。通过退火工艺优化了薄膜的导电性，使薄膜电阻约为40 Ω/□。在最佳浓度（1wt %）下，硅表面的少数载流子寿命增加了约3.3倍。研究表明，通过调节转速来优化薄膜厚度和均匀性，优化后器件的平均光伏转换效率达到12.42±1.1%（单个电池的最高效率为13.5%）。此外，在其他浓度下，效率至少提高了5%。
