中文摘要 聚(3,4-乙烯二氧噻吩) (PEDOT) 是染料敏化太陽能電池 (DSSC) 的優質電催化劑。然而，多孔 PEDOT 薄膜缺乏定向傳導路徑，導致電子傳輸速度較慢，電池效率較低。在這項研究中，銀奈米線（Ag NWs）被納入PEDOT薄膜中，構建PEDOT塗層的Ag NW複合薄膜，其中Ag NWs充當電荷傳輸的高速公路。該複合薄膜是透過三步驟製程（浸塗、刷塗和熱壓）將Ag NWs鋪展在錫摻雜氧化銦（ITO）玻璃上，然後透過電聚合塗覆PEDOT薄膜來建構。由PEDOT塗覆的Ag NW催化的DSSC在太陽光照下表現出9.22%的效率，透過提高短路電流密度，優於白金（9.09%的效率）和PEDOT（8.33%的效率）。進行化學態分析以確定 Ag NW 和 PEDOT 之間的相互作用。進行阻抗測量和量子化學計算以合理化 PEDOT 塗層銀奈米線的功能。由於其高透明度，所獲得的 DSSC 在背面照明下實現了 6.74% 的效率，證明其作為雙面 DSSC 的高度可行性。在 300-1000 lux的低強度正面照明下，DSSC 也表現出 14.05% 至 19.69% 的高效率。
英文摘要 Poly(3,4-ethylenedioxythiophene) (PEDOT) is a superior electrocatalyst for dye-sensitized solar cells (DSSCs). The porous PEDOT film, however, lacks directional conduction paths, resulting in slower electron transfer and lower cell efficiency. In this study, silver nanowires (Ag NWs) are incorporated into a PEDOT film to construct a PEDOT-coated Ag NW composite film, wherein the Ag NWs serve as highways for charge transport. The composite film is constructed by spreading Ag NWs on tin-doped indium oxide (ITO) glass via a three-step process (dip coating, brush painting, and thermal compression), followed by coating a PEDOT film via electropolymerization. The DSSC catalyzed by the PEDOT-coated Ag NW exhibited an efficiency of 9.22% under one-sun illumination, outperforming platinum (9.09% efficiency) and PEDOT (8.33% efficiency) by increasing the short-circuit current density. Chemical state analyses were performed to determine the interactions between the Ag NWs and PEDOT. Impedance measurements and quantum chemical calculations were conducted to rationalize the functionality of the PEDOT-coated Ag NWs. Owing to its high transparency, the resulting DSSC achieves an efficiency of 6.74% under rear illumination, demonstrating its high feasibility as a bifacial DSSC. The DSSC also exhibited high efficiencies ranging from 14.05% to 19.69% under front-side illumination at low intensities of 300–1000 lux.
