A novel design of thin-film crystalline silicon solar cell (TF C-Si-SC) is proposed and numerically analyzed. The reported SC has 1.0 µm thickness of C-Si with embedded dielectric silicon dioxide nanowires (NWs). The introduced NWs increase the light scattering in the active layer which improves the optical path length and hence the light absorption. The SC geometry has been optimized using particle swarm optimization (PSO) technique to improve the optical and electrical characteristics. The suggested TF C-Si-SC with two embedded NWs offers photocurrent density ([Formula: see text]) of 32.8 mA cm which is higher than 18 mA cm of the conventional thin film SC with an enhancement of 82.2%. Further, a power conversion efficiency of 15.9% is achieved using the reported SC.
提出了一种新型的薄膜晶体硅太阳能电池（TF C-Si-SC）并进行了数值分析。所报道的太阳能电池具有1.0 µm厚的C-Si，其中嵌入了介电二氧化硅纳米线（NWs）。引入的纳米线增加了有源层中的光散射，从而改善了光程长度，进而提高了光吸收。利用粒子群优化（PSO）技术对太阳能电池的几何结构进行了优化，以改善其光学和电学特性。所建议的带有两根嵌入纳米线的TF C-Si-SC的光电流密度（[公式：见正文]）为32.8 mA/cm²，高于传统薄膜太阳能电池的18 mA/cm²，提高了82.2%。此外，使用所报道的太阳能电池实现了15.9%的功率转换效率。
