溶液处理的银纳米线（Ag NW）薄膜被引入作为薄膜太阳能电池的透明电极。Ag NW电极在中等温度（低于100摄氏度）下通过在玻璃基板上的刮刀涂布来处理。这些电极的形态，光学和电学特性进行了研究作为一个功能的处理参数。对于太阳能电池应用，选择在450和800 nm之间具有90%的平均透明度和每平方10 Ω的薄层电阻率的Ag NW电极。发现Ag NW电极上的聚（3-己基噻吩-2，5-二基）：[6，6]-苯基-C61-丁酸甲酯（P3 HT：PCBM）太阳能电池的性能与氧化铟锡上的其它相同电池的性能相匹配。总的来说，已经实现了在透明Ag NW电极上具有2.5%效率的P3 HT：PCBM太阳能电池。
Solution processed silver nanowire (Ag NW) films are introduced as transparent electrodes for thin-film solar cells. Ag NW electrodes were processed by doctor blade-coating on glass substrates at moderate temperatures (less than 100 degrees C). The morphological, optical, and electrical characteristics of these electrodes were investigated as a function of processing parameters. For solar-cell application, Ag NW electrodes with an average transparency of 90% between 450 and 800 nm and a sheet resistivity of 10 O per square were chosen. The performance of poly(3-hexylthiophen-2,5-diyl):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) solar cells on Ag NW electrodes was found to match the performance of otherwise identical cells on indium tin oxide. Overall, P3HT:PCBM solar cells with an efficiency of 2.5% on transparent Ag NW electrodes have been realized.
