The efficiency of double-junction CIGS/Perovskite-based solar cells has significantly improved through recent research. This study presents a new plasmonic structure for these optical devices, utilizing cluster nanostructures to increase photon absorption between 650 and 1137 nm wavelength ranges. The proposed nanostructure includes two vertically coupled silver nanoparticles embedded at the center of the bottom active layer (CIGS) that absorb most of the incoming light to CIGS within the active layer. The electric field produced by the coupling of the nanoparticles has a superior performance. To analyze the effect of nanoparticle coupling on CIGS/Perovskite solar cell performance, evaluated the short-circuit current density and power conversion efficiency for single and cluster nanostructures with a single nanoparticle in the middle of CIGS. The structures with a single nanoparticle displayed J = 16.89 mA cm and PCE = 31.76%, while the cluster nanostructure represents J = 19 mA cm and PCE = 35.81%. Not only did the use of the cluster nanostructure significantly improve absorption and performance compared to the bare case, but it also exhibited a suitable improvement compared to the single nanoparticle.
通过最近的研究，基于双结铜铟镓硒/钙钛矿的太阳能电池效率有了显著提高。本研究为这些光学器件提出了一种新的等离子体结构，利用簇状纳米结构在650至1137纳米波长范围内增加光子吸收。所提出的纳米结构包括两个垂直耦合的银纳米颗粒，嵌入在底部活性层（铜铟镓硒）的中心，它们吸收活性层内大部分入射到铜铟镓硒的光。纳米颗粒耦合产生的电场具有优异的性能。为了分析纳米颗粒耦合对铜铟镓硒/钙钛矿太阳能电池性能的影响，评估了在铜铟镓硒中间有单个纳米颗粒的单纳米结构和簇状纳米结构的短路电流密度和功率转换效率。具有单个纳米颗粒的结构显示J = 16.89 mA/cm²和PCE = 31.76%，而簇状纳米结构的J = 19 mA/cm²和PCE = 35.81%。与裸片情况相比，簇状纳米结构的使用不仅显著提高了吸收和性能，而且与单个纳米颗粒相比也有适当的提高。
