鈣鈦礦光伏電池的水活化和熱活化動態(tài)鈍化 ▲ 作者:Wei-Ting Wang, Philippe Holzhey et al. ▲鏈接: https://www.nature.com/articles/s41586-024-07705-5 ▲摘要: 在此,我們報告了一種使用阻礙脲/硫代氨基甲酸酯鍵Lewis酸堿材料(HUBLA)的活性鈍化策略,其中具有水和熱活化特性的動態(tài)共價鍵可以動態(tài)修復(fù)鈣鈦礦,以確保設(shè)備的性能和穩(wěn)定性。暴露于濕氣或高溫下,HUBLA會產(chǎn)生新的試劑,并進一步鈍化鈣鈦礦中的缺陷。 這種鈍化策略實現(xiàn)了功率轉(zhuǎn)換效率(PCE)為25.1%的高性能器件。HUBLA設(shè)備在85攝氏度的氮氣中老化約1500小時后,其初始PCE保持在94%,在85攝氏度和30%相對濕度的空氣中老化1000小時后,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. |
