诸如氧化铟锡（ITO）的透明导电电极的存在限制了有机光伏器件的可靠性和成本价格，因为其易碎且昂贵。此外，柔性基板上的ITO电极的相对高的薄层电阻限制了单个电池的最大宽度。我们开发了一种替代的无ITO透明阳极，其基于溶液处理的高导电性PEDOT：PSS与印刷的集电格栅的组合。丝网印刷的银网格显示出典型的薄层电阻为1 Omega/平方，表面覆盖率为6.4-8%。具有4cm（2）的有效面积的柔性器件的效率比基于ITO的类似器件高得多。此外，由于这种复合阳极是溶液加工的，因此它是朝着低成本大面积加工迈出的一步。(C)2010 Elsevier B. V.保留所有权利。
The presence of a transparent conductive electrode such as indium tin oxide (ITO) limits the reliability and cost price of organic photovoltaic devices as it is brittle and expensive. Moreover, the relative high sheet resistance of an ITO electrode on flexible substrates limits the maximum width of a single cell. We have developed an alternative ITO-free transparent anode, based on solution processed high conductive PEDOT:PSS in combination with a printed current collecting grid. The screen printed silver grid demonstrates a typical sheet resistance of 1 Omega/square with 6.4-8% surface coverage. The efficiency of a flexible device with an active area of 4 cm(2) with such a grid is much higher than a similar device based on ITO. Furthermore, as this composite anode is solution-processed, it is a step forward towards low-cost large area processing. (C) 2010 Elsevier B.V. All rights reserved.
