我们提出了无ito的刚性和柔性单片有机太阳能电池，其有效面积为25平方厘米。该器件采用由氧化钼/银/硫化锌堆叠组成的透明绝缘体/金属/绝缘体阳极，其峰值透射率为80%，片电阻为3.6 52/0。中子反射表明，硫化锌在气界面处形成了比氧化钼更稳定的盖层。发现叶片涂层可以在刚性（玻璃）和柔性聚对苯二甲酸乙酯I基板上形成高质量的大面积薄膜，大大减少了材料消耗。由聚[N-9”-庚烷- 1-2,7-咔唑-氨基-5,5-（4',7'-二-2-噻基-2',1',3'-苯并噻唑）]（PCDTBT）和16,61-苯基-c -71-丁酸甲酯（PC70BM）混合而成的活性层组成的电池的功率转换效率为2.7%，比标准的itobic器件高40%。当使用柔性衬底时，没有观察到效率的损失。(C) 2014 Elsevier B.V.版权所有
We present ITO-free rigid and flexible monolithic organic solar cells with an active area of 25 cm2. The devices employ a transparent insulator/metal/insulator anode consisting of a molybdenum oxide/silver/ zinc sulfide stack that had a peak transmittance of 80% and a sheet resistance of 3.6 52/0. Neutron reflectometry showed that zinc sulfide formed a more stable capping layer at the air interface than molybdenum oxide. It was found that blade coating could be used to form good quality large area films on both rigid (glass) and flexible Epoly(ethylene terephthalate)I substrates with much reduced material consumption. Cells with an active layer comprised of a blend of poly[N-9"-heptadecany1-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (PCDTBT) and 16,61-phenyl-C-71-butyric acid methyl ester (PC70BM) gave a power conversion efficiency of 2.7%, which was 40% higher than a standard ITObased device. No loss in efficiency was observed when a flexible substrate was used. (C) 2014 Elsevier B.V. All rights reserved.
