在本研究中,我们将一种双功能有机二硫化物--二-5-(1-甲基四氮唑)二硫化物(T2)引入到钙钛矿型薄膜中,以改善平面钙钛矿型太阳能电池的性能和稳定性。结果表明,T2在PSCs中的两个主要作用是:由于T2与钙钛矿的相互作用,提高了钙钛矿晶体的质量;通过氧化还原反应消除了Pb0和I0缺陷,允许在此过程中T2的再生。我们实现了PSCs的功率转换效率(PCE),T2为20.67%,比对照器件(17.9%)提高了15%。此外,具有T2的PSC器件表现出更高的操作稳定性和存储稳定性。S手术140时PCE无明显下降。该设备在环境条件(20°C,40%湿度)下,在没有封装的情况下,2个月保持了95%的初始效率。
In this study, we used a bifunctional organic disulfide, di-5-(1-methyltetrazole) disulfide (T2), in perovskite films to improve the performance and stability of planar perovskite solar cells (PSCs). The results indicate two major functions of T2in PSCs: improving the perovskite crystal quality due to the interaction between T2and perovskite and eliminating Pb0and I0defects by redox reaction, allowing for the regeneration of T2in the process. We achieved a power conversion efficiency (PCE) of PSCs with T2of 20.67%, a 15% increase compared to the control device (17.9%). Furthermore, PSC devices with T2exhibited enhanced operational stability and storage stability. During 140 s of operation, there was no evident decrease of PCE. The device maintained 95% of its initial efficiency without encapsulation under ambient conditions (20 °C, 40% humidity) for 2 months.
