中文摘要 近年來,混合鈣鈦礦型太陽電池(PSC)因其成本低、製作簡單、光電轉換效率高等優點而備受關注。然而,溶液處理的鈣鈦礦薄膜通常表現出嚴重的結構紊亂,導致晶格和晶界表面的離子缺陷。在此,我們開發了一系列編碼為CS0CS1CS2D-π-A型紫質,它們可以有效鈍化鈣鈦礦表面,增加VOCFF,減少滯後效應,提高功率轉換效率,使其高於22%,並提高器件穩定性。本研究結果表明,供體-π-受體型紫質衍生物是一種很有前途的鈍化劑,可以改善PSCs的電池性能。
英文摘要 In recent years, hybrid perovskite solar cells (PSCs) have attracted much attention owing to their low cost, easy fabrication, and high photoelectric con version efficiency. Nevertheless, solution-processed perovskite films usually show substantial structural disorders, resulting in ion defects on the surface of lattice and grain boundaries. Herein, a series of D–π–A porphyrins coded as CS0, CS1, and CS2 that can effectively passivate the perovskite surface, increase VOC and FF, reduce the hysteresis effect, enhance power conversion efficiency to be higher than 22%, and improve the device stability is developed. The results in this study demonstrated that the donor-π-acceptor type porphyrin derivatives are promising passivators that can improve the cell performance of PSCs.
