中文摘要 開發具有擴展π共軛以及與太陽光和螢光燈光譜匹配的光敏劑對於在染料敏化太陽能電池（DSSC）中實現高功率轉換效率（PCE）至關重要。本研究開發了一系列新型蒽基光敏劑AMO1–AMO4。 該系列設計有大體積改性Hagfeldt 供體以抑制不需要的分子聚集、雙蒽基團以增強π 共軛、乙炔基團以改善分子平面性，以及四個不同的受體來微調它們的光物理和電化學特性。使用兩種銅錯化物做電解質 CuI/II(dmp)2 和 CuI/II(dmodmbp)2 並比較搭配新型染料AMO1-AMO4 在 DSSC 中的性能。在所研究的染料中，以 CuI/II(dmodmbp)2 介導的 AMO2 在陽光照射和在 T5 照明（6000 lux）下，PCE 高達 34.64%。這些結果顯示了蒽橋敏化 DSSC 在室內和室外應用中的巨大潛力。
英文摘要 The development of photosensitizers with extendedπ-conjugation and spectral matching to sunlight and fluorescent light is crucial for achieving high powerconversion efficiency (PCE) in dye-sensitized solar cells (DSSCs). This study presents a series of novel anthracene-based photosensitizers, AMO1–AMO4.This series has been designed with bulky modified Hagfeldt donors to suppress undesired molecular aggregation, double anthracene groups for enhanced π-conjugation, acetylene groups for improved molecular planarity, and four distinct acceptors to fine-tune their photophysical and electrochemical properties. Theperformance of the novel dyes in DSSCs is investigated using two copper redox shuttles, CuI/II(dmp)2 and CuI/II(dmodmbp)2 . Among the investigated dyes, AMO2 mediated with CuI/II(dmodmbp)2 exhibits the highest power conversion efficiency (PCE) of 10.05% (JSC = 13.72 mA·cm2, VOC = 1.035 V, and FF = 0.71) under sunlight illumination and an outstanding PCE of 34.64% under T5 illumination (6000 lux). These achievements underscore the remarkable potential of anthracene-bridged sensitized DSSCs in indoor and outdoor applications.
