摘要：

本文设计了一种可以通过刮涂方法制备的基于银纳米线(AgNWs)的柔性复合透明电极,并以此为基础实现了高性能柔性聚合物太阳能电池的制备。基于银纳米线的柔性复合薄膜(APA)由银纳米线(AgNWs),聚乙烯醇缩丁醛(PVB)和铝掺杂氧化锌(AZO)纳米粒子在低温下通过多层刮涂的方法制备。 APA透明复合薄膜在550 nm处透光率达到90.90%,面电阻低至13.01 Ω/sq,在柔性基底上具有很高的粘附性。在透明的APA/聚对苯二甲酸乙二醇酯(PET)基底上制备的柔性聚合物太阳能电池(PSCs),能量转换效率达到5.47%。而且以5 mm为曲率半径,经过1000次循环弯曲实验,电池的能量转换效率仅下降了14%。

Abstract:

A high performance flexible polymer solar cells(PSCs) are obtained by using a flexible, transparent composite electrode based on silver nanowire(AgNW) with doctor blading method. The AgNW-based flexible composite film(APA) consisting of AgNWs, polyvinyl butyral(PVB) and Al-doped ZnO(AZO) nanoparticles was readily prepared by multi-layer doctor blading on the poly(ethylene terephthalate)(PET) substrate at moderate temperature. The transparent APA composite film prepared on the PET substrate exhibits superior opto-electrical properties with a high transmittance of 90.90% at 550 nm and a low sheet resistance of 13.01 Ω/sq. The flexible PSCs employing the transparent APA/PET substrate obtain power convention efficiency(PCE) of 5.47%. Moreover, the PCE falls only 14% after bending for 1000 cycles with a bending radius of 5 mm.
