To achieve high-performance perovskite solar cells, this study meticulously investigates the synergistic effects of SiO nanoparticles and Au nanopyramids as antireflective and plasmonic structures, respectively. Utilizing the finite-difference time-domain (FDTD) method, the effectiveness of four dielectric nanoparticles (SiO, AlO, ZnO, and TiO) as antireflection coatings is comprehensively analyzed. The optimum structure achieved a notable 12.2% increase in light absorption over the 300 nm to 800 nm wavelength range, considering absorption of Au nanopyramids as loss. This enhancement is attributed to a 6.1% reduction in light reflection by the dielectric nanoparticles and a 6.1% increase due to near-field enhancement around the Au nanopyramids. The integration of Au nanopyramids leads to superior solar cell performance because their wavelength resonance is located in the region greater than 600 nm. The J-V curve data obtained from SCAPS simulations further confirms the enhanced performance, revealing a significant increase in short-circuit current density and overall power conversion efficiency. Additionally, the device based on Au spherical nanoparticles, square and rectangular plasmonic nanostructures have also been studied to investigate the importance of the plasmonic structure geometry. These compelling findings underscore the transformative potential of combining antireflective and plasmonic strategies with the appropriate structure for exceptional light management in perovskite solar cells.
为了实现高性能钙钛矿太阳能电池，本研究精心探究了SiO纳米颗粒和Au纳米金字塔分别作为减反射结构和等离子体结构的协同效应。利用时域有限差分（FDTD）方法，全面分析了四种介电纳米颗粒（SiO、AlO、ZnO和TiO）作为减反射涂层的有效性。考虑到Au纳米金字塔的吸收为损耗，优化结构在300nm至800nm波长范围内实现了显著的12.2%的光吸收增加。这种增强归因于介电纳米颗粒使光反射降低了6.1%，以及Au纳米金字塔周围近场增强导致光吸收增加了6.1%。Au纳米金字塔的集成带来了卓越的太阳能电池性能，因为其波长共振位于大于600nm的区域。从SCAPS模拟获得的J-V曲线数据进一步证实了性能的增强，显示短路电流密度和整体功率转换效率显著提高。此外，还研究了基于Au球形纳米颗粒、方形和矩形等离子体纳米结构的器件，以探究等离子体结构几何形状的重要性。这些引人注目的发现强调了将减反射和等离子体策略与适当结构相结合，以在钙钛矿太阳能电池中实现卓越光管理的变革潜力。
