有机光伏（OPV）太阳能电池，可以简单地从溶液中处理，是学术界和工业界的焦点，因为它们具有巨大的潜力，以降低成本。开发完全溶液处理的OPV技术的一个巨大挑战是设计性能良好的电极系统，允许替代ITO。已经讨论了几种溶液处理的电极系统，但它们中没有一种可以与ITO的性能相匹配。在这里，我们报告了高效的ITO和完全的解决方案处理的半透明倒置有机太阳能电池的基础上银纳米线（AgNW）电极。为了证明这些AgNW电极的潜力，它们被用作底部和顶部电极。记录器件实现了高达63.0%的填充因子，这与基于ITO的参考器件相当。这些结果为全印刷有机太阳能电池提供了重要进展，并表明无ITO、透明以及不透明的有机太阳能电池确实可以完全溶液加工而没有损失。
Organic photovoltaic (OPV) solar cells that can be simply processed from solution are in the focus of the academic and industrial community because of their enormous potential to reduce cost. One big challenge in developing a fully solution-processed OPV technology is the design of a well-performing electrode system, allowing the replacement of ITO. Several solution-processed electrode systems were already discussed, but none of them could match the performance of ITO. Here, we report efficient ITO-free and fully solution-processed semitransparent inverted organic solar cells based on silver nanowire (AgNW) electrodes. To demonstrate the potential of these AgNW electrodes, they were employed as both the bottom and top electrodes. Record devices achieved fill factors as high as 63.0%, which is comparable to ITO based reference devices. These results provide important progress for fully printed organic solar cells and indicate that ITO-free, transparent as well as non-transparent organic solar cells can indeed be fully solution-processed without losses.
