This report computationally investigates the relative influence of absorber layer crystallinity and the nature of interfaces in lead-based (toxic) and tin-based (non-toxic) perovskite solar cells using SCAPS-1D. The absorber layer crystallinity was modelled in terms of varying charge carrier mobility and defect density while the interfacial behaviour was modelled through varying defect density at the electron transport material (ETM)/perovskite and perovskite/hole transport material (HTM) interfaces. The results suggest that tuning of the aforementioned parameters plays a critical role in improving the efficiency of perovskite solar cells. In-depth analysis of the results elucidates that the performance of both types of simulated structure is critically dependent on the crystallinity of the perovskite absorber layer. Furthermore, the performance of the lead-based structure is more dependent on the nature of the ETM/perovskite interface than that of the perovskite/HTM interface w...

吸收层结晶度和界面缺陷状态相互作用对铅基和锡基钙钛矿太阳能电池性能影响的比较研究

该报告通过计算研究了使用SCAPS-1D的铅基（有毒）和锡基（无毒）钙钛矿太阳能电池中吸收层结晶度的相对影响以及界面性质。根据变化的电荷载流子迁移率和缺陷密度对吸收层的结晶度进行建模，而通过改变电子传输材料（ETM）/钙钛矿和钙钛矿/空穴传输材料（HTM）界面处的缺陷密度对界面行为进行建模。结果表明，前述参数的调节在提高钙钛矿太阳能电池的效率中起关键作用。对结果的深入分析表明，两种类型的模拟结构的性能都主要取决于钙钛矿吸收层的结晶度。此外，
