摘要: V2O5具有优异的稳定性、光学和电学性能,且价格低廉,能有效提高太阳能电池的光电性能,是一种新型的空穴传输层材料。采用SCAPS-1D模拟软件,设计并构建了一种结构为FTO/ZnO-NR/ CH3NH3Pb(I1-x Cl x3/V2O5/C的钙钛矿太阳能电池。通过对CH3NH3Pb(I1-x Cl x3材料厚度与带隙的优化调控研究发现,当其厚度为0.8 μm、带隙为1.5 eV时,器件的光电转换效率(PCE)达到最大值26.95%。同时进一步研究了ZnO-NR的掺杂浓度和CH3NH3Pb(I1-x Cl x3/V2O5界面缺陷对器件性能的影响。

Abstract: V2O5 has outstanding stability, superior optical and electrical properties, and cost-efficient. This material can significantly enhance the photoelectrical performance of solar cells and represents an innovative type of hole-transport layer material. A perovskite solar cell featuring the architecture of FTO/ZnO-NR/ CH3NH3Pb(I1-x Cl x3/V2O5/C was meticulously designed utilizing the SCAPS-1D simulation software. Through systematic optimization and adjustment of the thickness and band gap of the CH3NH3Pb(I1-x Cl x3 material, it was determined that the maximum photoelectrical conversion efficiency (PCE) of 26.95% was achieved when the thickness and band gap were 0.8 μm and 1.5 eV, respectively. Concurrently, the influences of the ZnO-NR doping concentration and the interfacial defects at the CH3NH3Pb(I1-x Cl x3/V2O5 on device performance were also investigated.
