摘要

由于制造成本低、功率转换效率高(PCE),过氧化物太阳能电池(PSCs)已成为传统硅太阳能电池的一种有前途的替代品。利用卤化铅包晶石作为包晶石太阳能电池的吸收层一直受到两大问题的阻碍:铅中毒和稳定性问题。这些障碍极大地阻碍了这一尖端技术的产业化。鉴于铅在包晶体太阳能电池中的有害影响,研究人员已将注意力转移到无铅金属卤化物包晶体的探索上。然而,目前铅基过氧化物的替代品性能不佳,因此促使人们进一步研究这一问题。本研究的主要目的是研究如何将 Cu2O 作为空穴传输层与无铅金属卤化物包晶石(CsSn0.5Ge0.5I3)结合使用,以实现更优越的性能。通过细致的实验,所建议的模型通过优化几个关键变量取得了卓越的成果。这些变量包括吸收层(CsSn0.5Ge0.5I3)的厚度、缺陷密度和掺杂密度,以及与各层相关的背接触功函数和工作温度。通过对吸收层厚度和缺陷密度、掺杂密度和背接触功等关键方面的全面研究,所提出的 FTO/PC60BM/CsSn0.5Ge0.5I3/Cu2O/Au 太阳能电池结构超越了之前的配置。该结构还与多种电子传输元件进行了比较,得出的结论是,由于使用了 PC60BM 作为电子传输层,而且改进了电子提取程序,因此所提出的模型功能更优越。最后,所提出的模型达到了 31.56 mA/cm-2、1.12 V、81.47% FF 和 27.72% PCE 的优化值。作为这项研究的成果,所研究的结构可能是最终利用过氧化物制造无铅太阳能电池的最佳竞争者。

Enhancing CsSn0.5Ge0.5I3 Perovskite Solar Cell Performance via Cu2O Hole Transport Layer Integration
Perovskite solar cells (PSCs) have emerged as a promising alternative to traditional silicon solar cells due to their low cost of fabrication and high power conversion efficiency (PCE). The utilization of lead halide perovskites as absorber layers in perovskite solar cells has been impeded by two major issues: lead poisoning and stability concerns. These hindrances have greatly impeded the industrialization of this cutting-edge technology. In light of the harmful effects of lead in perovskite solar cells, researchers have shifted their attention to exploring lead-free metal halide perovskites. However, the present alternatives to lead-based perovskite exhibit poor performance, thus prompting further inquiry into this matter. The primary objective of this research is to investigate the use of Cu2O as a hole transport layer in combination with lead-free metal halide perovskite (CsSn0.5Ge0.5I3) to achieve superior performance. Through meticulous experimentation, the suggested model has achieved outstanding results by optimizing several key variables. These variables include the thickness of the absorber layer (CsSn0.5Ge0.5I3), defect density, and doping densities, as well as the back contact work function and the operating temperature associated with each layer. The proposed FTO/PC60BM/CsSn0.5Ge0.5I3/Cu2O/Au solar cell structure surpassed prior configurations by comprehensively examining key aspects such as absorber layer thickness and defect density, doping densities, and back contact work. The structure has been also compared with multiple electron transport elements and concluded that the proposed model functions superior due to the use of PC60BM as an electron transport layer and it has an improved electron extraction procedure. Finally, the proposed model has achieved the optimized values as of 31.56 mA/cm-2, of 1.12 V, FF of 81.47%, and PCE of 27.72%. As a consequence of this research, the investigated structure may be an excellent contender for the eventual creation of lead-free solar power cells made from perovskite.
