中文摘要 本研究設計含有噻吩基給體與電子受體基團的紫質分子，作為自組裝單分子層 (SAMs) 以鈍化錫鈣鈦礦太陽能電池的缺陷，效率最高達 8.65% (MC-4)，展現出更佳的電荷傳輸與擷取能力，為紫質應用於 TPSCs 開闢了新方向。
英文摘要 The MC-series porphyrins, incorporating a variety of thiophene- and dithiophene-containing donor groups, offer an effective passivation strategy to eliminate Sn2+ defects on the surface of tin perovskite. Additionally, the C(15) position of the porphyrin core is linked to various electron-accepting groups, such as 2,1,3-benzothiadiazole, 4-(2,3-diphenylquinoxalin-5-yl)benzoic acid and an indacenodithiophene unit connected to carboxylic acid or cyanoacrylic acid. These groups act as self-assembled monolayers (SAMs) on indium tin oxide (ITO) substrates for tin-based perovskite solar cells (TPSCs). This study is the first example to report the use of porphyrin as SAM for TPSCs. In the presence of SAMs, the devices achieved efficiencies in the following order: MC-4 (8.65%) > MC-3 (6.19%) > MC-2 (5.06%) > MC-1 (5.03%). The outstanding performance of the MC-4 device is attributed to its retarded charge recombination, increased hole mobility, and superior hole-extraction capability. This approach offers a promising pathway for further developing porphyrin-based TPSCs.
發表成果與本中心研究主題相關性 太陽能電池可將光轉換成電，其中鈣鈦礦太陽能電池中開發新型自組裝單分子層 (SAMs) 以鈍化錫鈣鈦礦太陽能電池的缺陷以期提高光電轉換效率的目標在永續農業發展上的重要性不容小覷，因為光源可以是大自然的太陽光，可以是人造的室內弱光，而光則是在農業發展上不可或缺的條件之一。
