反转有机光伏（OPV）层序面临的挑战是制备选择性接触的底部阴极，并在倒置结构中实现适合载流子收集的形态。作者报道了在氧化铟锡顶部基于溶液处理的氧化钛界面层创建了一种高效的电子选择性底部接触。使用邻二甲苯作为溶剂创建了一个高效的载流子收集网络，几乎没有垂直相分离，为常规和倒置太阳能电池都提供了足够的性能。作者展示了经AM 1.5校准的功率转换效率超过3%的倒置层序有机光伏电池。（c）2006美国物理学会
The challenge to reversing the layer sequence of organic photovoltaics (OPVs) is to prepare a selective contact bottom cathode and to achieve a suitable morphology for carrier collection in the inverted structure. The authors report the creation of an efficient electron selective bottom contact based on a solution-processed titanium oxide interfacial layer on the top of indium tin oxide. The use of o-xylene as a solvent creates an efficient carrier collection network with little vertical phase segregation, providing sufficient performance for both regular and inverted solar cells. The authors demonstrate inverted layer sequence OPVs with AM 1.5 calibrated power conversion efficiencies of over 3%. (c) 2006 American Institute of Physics.
