It is important to lower the cost and stability of the organic-inorganic hybrid perovskite solar cells (PSCs) for industrial application. The commonly used hole transport materials (HTMs) such as Spiro-OMeTAD, poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA) and poly(3-hexylthiophene-2,5-diyl) (P3HT) are very expensive. Here, 3,4-ethylenedioxythiophene (EDOT) monomers are in-situ polymerized on the surface of graphene oxide (GO) as PEDOT-GO film. Compared to frequently used polystyrene sulfonic acid (PSS), GO avoids the corrosion of the perovskite and the use of HO solvent. The composite PEDOT-GO film is between carbon pair electrode and perovskite layer as hole transport layer (HTL). The highest power conversion efficiency (PCE) is 14.09%.
降低有机-无机杂化钙钛矿太阳能电池（PSC）的成本并提高其稳定性对于工业应用而言至关重要。常用的空穴传输材料（HTM），如Spiro-OMeTAD、聚[双（4-苯基）（2,4,6-三甲基苯基）胺]（PTAA）和聚（3-己基噻吩-2,5-二亚基）（P3HT）都非常昂贵。在此，3,4-亚乙基二氧噻吩（EDOT）单体在氧化石墨烯（GO）表面原位聚合形成聚3,4-乙撑二氧噻吩-氧化石墨烯（PEDOT-GO）薄膜。与常用的聚苯乙烯磺酸（PSS）相比，GO避免了对钙钛矿的腐蚀以及对HO溶剂的使用。复合PEDOT-GO薄膜作为空穴传输层（HTL）置于碳对电极和钙钛矿层之间。最高功率转换效率（PCE）为14.09%。
