[交流] 钙钛矿光伏电池的水活化和热活化动态钝化

钙钛矿光伏电池的水活化和热活化动态钝化

▲摘要:

在此,我们报告了一种使用阻碍脲/硫代氨基甲酸酯键Lewis酸碱材料(HUBLA)的活性钝化策略,其中具有水和热活化特性的动态共价键可以动态修复钙钛矿,以确保设备的性能和稳定性。暴露于湿气或高温下,HUBLA会产生新的试剂,并进一步钝化钙钛矿中的缺陷。

这种钝化策略实现了功率转换效率(PCE)为25.1%的高性能器件。HUBLA设备在85摄氏度的氮气中老化约1500小时后,其初始PCE保持在94%,在85摄氏度和30%相对湿度的空气中老化1000小时后,其初始PCE保持在88%。

▲ Abstract:

Here we report a living passivation strategy using a hindered urea/thiocarbamate bond Lewis acid–base material (HUBLA), where dynamic covalent bonds with water and heat-activated characteristics can dynamically heal the perovskite to ensure device performance and stability. Upon exposure to moisture or heat, HUBLA generates new agents and further passivates defects in the perovskite. This passivation strategy achieved high-performance devices with a power conversion efficiency (PCE) of 25.1 per cent. HUBLA devices retained 94 per cent of their initial PCE for approximately 1,500 hours of ageing at 85 degrees Celsius in nitrogen and maintained 88 per cent of their initial PCE after 1,000 hours of ageing at 85 degrees Celsius and 30 per cent relative humidity in air.
