摘要

过氧化物太阳能电池(PSC)的最高认证效率已达到 26.7%。然而,低温溶液法制备的过氧化物薄膜表面缺陷密度高,载流子传输层与过氧化物层(PVK)之间能量不匹配,极大地限制了过氧化物太阳能电池性能的提高。引入钝化剂对包晶石界面和晶界进行改性,可以降低缺陷密度,有效协调能级,提高器件的效率和稳定性。在 PVK 和空穴传输层(HTL)的界面上引入了具有多个活性位点的路易斯碱分子 5-氨基-1,3,4-噻二唑-2-硫醇(AMTD)。AMTD 上的富电子基团(如 = S、-S-、-NH2、-N)可钝化界面和晶界上的正电缺陷,提高载流子传输效率。通过优化界面能级阵列,可实现更高效的电荷传输。此外,AMTD 的改性对包晶石具有显著的保护作用,可抑制环境中的湿气侵蚀。因此,经过 AMTD 优化的器件实现了 24.13% 的功率转换效率 (PCE),而原始器件的效率仅为 21.62%。器件的稳定性也大大提高。

Efficient and stable perovskite solar cells based on multi-active sites 5-amino-1,3,4-thiadiazole-2-thiol modified interface
The highest certification efficiency of perovskite solar cells (PSCs) has reached 26.7 %. However, the high defect density on the surface of perovskite films prepared by low temperature solution method and the energy mismatch between the carrier transport layers and perovskite layer (PVK) greatly limit the performance improvement of PSCs. The introduction of passivating agent to modify the perovskite interface and grain boundary can reduce the defect density, coordinate the energy level effectively, and improve the efficiency and stability of devices. A Lewis base molecule 5-amino-1,3,4-thiadiazole-2-thiol (AMTD) with multiple active sites is introduced at the interface between PVK and hole transport layer (HTL). The electron-rich groups, such as = S, –S–, –NH2, –N on AMTD, passivate the positive electrical defects on the interface and grain boundary, and increase carrier transport efficiency. The interfacial energy level array is optimized to achieve more efficient charge transportation. In addition, the modified of AMTD has a significant protective effect on the perovskite, which inhibit the moisture erosion of in environment. Consequently, the AMTD-optimized device achieves a power conversion efficiency (PCE) of 24.13 %, compared to the efficiency of 21.62 % for pristine device. The stability of the devices is improved greatly.
