The perovskite solar cells (PSCs) and organic solar cells (OSCs) with high performance were fabricated with transfer-printed top metal electrodes. We have demonstrated that PSCs and OSCs with the top Au electrodes fabricated by using the transfer printing method have comparable or better performance than the devices with the top Au electrodes fabricated by using the conventional thermal evaporation method. The highest PCE of the PSCs and OSCs with the top electrodes fabricated using the transfer printing method achieved 13.72% and 2.35%, respectively. It has been investigated that fewer defects between the organic thin films and Au electrodes exist by using the transfer printing method which improved the device stability. After storing the PSCs and OSCs with the transfer-printed electrodes in a nitrogen environment for 97 and 103 days without encapsulation, the PSCs and OSCs still retained 71% and 91% of their original PCEs, respectively.
采用转印顶金属电极制备了高性能的钙钛矿太阳能电池（PSCs）和有机太阳能电池（OSCs）。我们已经证明，采用转印印刷方法制备的顶 Au 电极的 PSCs 和 OSCs 的性能与采用传统热蒸发方法制备的器件相当或更好。采用转印印刷方法制备顶电极的 PSCs 和 OSCs 的最高光电转换效率分别达到了 13.72%和 2.35%。研究发现，采用转印印刷方法可以减少有机薄膜和 Au 电极之间的缺陷，从而提高器件的稳定性。在氮气环境中未封装的情况下，分别储存 97 天和 103 天后，PSCs 和 OSCs 仍分别保留其原始光电转换效率的 71%和 91%。
