中文摘要 自組裝單層 (SAMs) 具有易於進行介面修飾的優勢，可顯著提高裝置效能。在這項研究中，我們報告了一系列新的羧酸官能化紫質衍生物的設計和合成，即AC-1、AC-3和AC-5，並首次提出了一種利用大尺寸紫質衍生物的策略。紫質的 π 部分作為主體，用於連接反式鈣鈦礦太陽能電池（PSC）配置中的氧化銦錫（ITO）電極和鈣鈦礦活性層。紫質的多電子特性有利於電洞轉移和 SAM 的形成，從而形成緻密的表面，從而最大限度地減少缺陷。全面的光譜和動力學研究表明，雙錨定AC-3和AC-5增強了ITO上的SAM，鈍化鈣鈦礦層，並作為促進電洞傳輸的管道，從而顯著提高PSC的性能。採用 AC-5 SAM 的反式 PSC 可高達 23.19% 太陽能效率和 84.05% 的高填充因子。這項工作提出了一項新穎的分子工程策略，用於對 SAM 進行功能化，以調整能階、分子偶極、堆積方向，以實現穩定且高效的太陽能轉換性能。重要的是，我們的全面調查揭示了相關機制，有助於 PSC 的未來發展。
英文摘要 Self-assembled monolayers (SAMs) offer the advantage of facile interfacial modification, leading to significant improvements in device performance. In this study, we report the design and synthesis of a new series of carboxylic acid-functionalized porphyrin derivatives, namely AC-1, AC-3, and AC-5, and present, for the first time, a strategy to exploit the large π-moiety of porphyrins as a backbone for interfacing the indium tin oxide (ITO) electrode and perovskite active layer in an inverted perovskite solar cell (PSC) configuration. The electron-rich nature of porphyrins facilitates hole transfer and the formation of SAMs, resulting in a dense surface that minimizes defects. Comprehensive spectroscopic and dynamic studies demonstrate that the double-anchored AC-3 and AC-5 enhance SAMs on ITO, passivate the perovskite layer, and function as conduits to facilitate hole transfer, thus significantly boosting the performance of PSCs. The champion inverted PSC employing AC-5 SAM achieves an impressive solar efficiency of 23.19 % with a high fill factor of 84.05 %. This work presents a novel molecular engineering strategy for functionalizing SAMs to tune the energy levels, molecular dipoles, packing orientations to achieve stable and efficient solar performance. Importantly, our comprehensive investigation has unraveled the associated mechanisms, offering valuable insights for future advancements in PSCs.
