摘要: | 鈣鈦礦有機-無機金屬鹵化物太陽能電池因為有經濟實惠且高性能的優勢,因此可以做為替代傳統矽電池方案。儘管近年來鈣鈦礦太陽能電池的技術取得了重大進步,但穩定性和大規模生產仍然是人們持續關注的問題。 在這項研究中,我們透過鍵合丙二醇(PPG)與苯基-C71-丁酸甲酯(PC71BM)合成一種新型功能性富勒烯聚合物,命名為PCBPPG。 透過 PPG 和 PC71BM 之間的簡單酯交換過程獲得的PCBPPG可用作倒置的雙陽離子鈣鈦礦太陽能電池元件 (PSC) 的添加劑。 我們的研究顯示,添加PCBPPG可以提高了 PSC 元件的光伏能源轉換效率 (PCE)。 優化PCE可因歸於 PCBPPG 的雙重功能:通過聚合物成分(PPG)誘導的異質成核來改善鈣鈦礦形態,同時由於富勒烯成分(PC71BM)而保持良好的光電性能。 重要的是,添加 PCBPPG 的 PSC 元件在環境空氣中表現出更高的穩定性。我們的研究結果有助於開發高性能聚合物添加劑應用於PSCs的發展。 Perovskite organic-inorganic metal halide-based solar cells are a cost-effective and high-performing alternative to conventional silicon cells however, stability and large-scale production remain as ongoing concerns despite significant technological advancements. In this study, we examined the synthesis and utilization of a novel polymer functionalized fullerene material by bonding propylene glycol (PPG) with phenyl-C71-butyric acid methyl ester (PC71BM), named PCBPPG. Obtained through an easy transesterification process between PPG and PC71BM, this material serves as an additive in inverted dual-cation perovskite solar cell devices (PSC). Our research revealed that the incorporation of PCBPPG led to improved power conversion efficiency (PCE) of PSC devices. This enhancement can be attributed to the dual functions of PCBPPG: improving perovskite morphology achieved through heterogenous nucleation induced by the polymer component (PPG), while maintaining favorable optoelectronic properties owing to the fullerene component (PC71BM). Importantly, PCBPPG-incorporated PSC devices showed improved stability in ambient air. Our results help pave the way for the development of high-performance polymer-based additives for PSCs. |
