论文摘要
我们对无毒，无铅的钙钛矿太阳能电池（PSC）进行了模拟研究，其中CS2Agbibr6，P3HT，ZnO纳米棒和C分别用作吸收层，孔传输层，电子传输层和背部接触。在600 nm的最佳吸收器厚度下，该设备的最大功率转换效率为4.48％。当电子亲和力设置为3.3 eV和4.6 eV的P3HT和ZnO纳米棒时，PSC最佳运行。此外，在选择适当的掺杂添加剂和掺杂水平时，应称量P3HT的孔迁移率和受体浓度。此外，最佳背部接触功能和吸收器缺陷密度分别为5.2 eV和1E15 cm-3。我们还观察到辐射重组速率和不同电荷传输层对设备性能的影响。总体而言，这项研究的仿真结果将为制造环境良性PSC提供深刻的指导。
We carried out simulative investigations on a non-toxic, lead-free perovskite solar cell (PSC), where Cs2AgBiBr6, P3HT, ZnO nanorod, and C were utilized as the absorber layer, hole transport layer, electron transport layer, and back contact, respectively. At 600 nm optimum absorber thickness, the device achieved a maximum power conversion efficiency of 4.48%. The PSC operated optimally when the electron affinities were set at 3.3 eV and 4.6 eV for P3HT and ZnO nanorod, respectively. Moreover, the hole mobility and acceptor concentration of P3HT should be weighed during the choosing of appropriate doping additives and doping levels. Besides, the optimum back contact work function and absorber defect density were found to be 5.2 eV and 1E15 cm-3, respectively. We also observed the effect of radiative recombination rates and different charge transport layers on the device's performance. Overall, this study's simulation results will provide insightful guidance towards fabricating an environmentally benign PSC.
