Abstract To demonstrate efficient and reliable indium thin oxide (ITO)-free organic solar cells (OSCs), we fabricated highly conductive poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) electrodes by two-step brush-painting of PEDOT:PSS and dimethyl sulfoxide (DMSO). While one-step brush-painted electrodes with PEDOT:PSS and DMSO mixed solution showed large deviation in morphology and efficiency, uniform and highly conductive PEDOT:PSS electrodes were obtained by successive brush-painting of PEDOT:PSS and DMSO, respectively. ITO-free OSC exhibiting power conversion efficiency (PCE) of 3.74% was successfully demonstrated by optimized successive brush-painting.

用于无 ITO 有机太阳能电池的两步刷涂 PEDOT:PSS 电极

摘要 为了展示高效可靠的无铟薄氧化物 (ITO) 有机太阳能电池 (OSC)，我们通过两步刷法制备了高导电性聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）电极。 - PEDOT:PSS 和二甲基亚砜 (DMSO) 的涂装。虽然用 PEDOT:PSS 和 DMSO 混合溶液一步刷涂电极在形态和效率上表现出很大的偏差，但通过连续刷涂 PEDOT:PSS 和 DMSO 获得了均匀且高导电性的 PEDOT:PSS 电极。通过优化的连续刷涂成功证明了无 ITO OSC 的功率转换效率 (PCE) 为 3.74%。
