Abstract

The absorbing layer thickness is a crucial parameter that significantly impacts the performance of perovskite solar cells (PSCs). In this study, we investigated the influence of the thickness of absorbing layer on the performance of silver-doped NaZnBr3 perovskite solar cells using the one-dimensional solar cell capacitance simulator (SCAPS-1D) software. The absorbing layer thickness was varied in the range of 0.1 to 1.3 µm. The initial solar cell after simulation gave an open-circuit voltage (Voc) of 1.174 V, short circuit current density (Jsc) of 14.012 mA/cm2, fill factor (FF) of 79.649%, and the power conversion efficiency (PCE) of 13.101%. For the optimized thickness of the perovskite layer of 1.0 µm, the following solar cell characteristics were obtained: Voc = 1.197 V, Jsc = 18.184 mA·cm–2, FF = 79.110%, and PCE = 17.215%. A 31% and 30% increase of the PCE and Jsc, respectively, was observed for the optimized device parameters as compared to the initial ones. Such finding confirms the premise for excellent photon management and enhancement of PSCs performance by selecting the thickness of absorbing layer.
钙钛矿厚度对掺银NaZnBr3钙钛矿太阳能电池性能的影响
吸收层厚度是影响钙钛矿太阳能电池性能的关键参数。在本研究中,我们利用一维太阳能电池电容模拟器(SCAPS-1D)软件研究了吸收层厚度对掺银NaZnBr3钙钛矿太阳能电池性能的影响。吸收层厚度在0.1 ~ 1.3µm范围内变化。模拟后的初始太阳能电池开路电压(Voc)为1.174 V,短路电流密度(Jsc)为14.012 mA/cm2,填充系数(FF)为79.649%,功率转换效率(PCE)为13.101%。当钙钛矿层厚度为1.0µm时,获得的太阳能电池性能为:Voc = 1.197 V, Jsc = 18.184 mA·cm-2, FF = 79.110%, PCE = 17.215%。与初始参数相比,优化后的PCE和Jsc分别提高了31%和30%。这一发现证实了通过选择吸收层厚度来实现优异的光子管理和提高psc性能的前提。
