摘要
银纳米线(AgNWs)顶电极是全溶液加工型有机太阳能电池(OSCs)的重要组成部分.然而,在涂布AgNWs乙醇溶液时,对下层空穴传输层有一定洗脱损坏.本文提出对空穴传输层聚(3,4-乙烯二氧噻吩)∶全氟磺酸离子聚合物(PEDOT∶F)进行交联,以提升其抗溶剂渗透能力.通过引入交联剂聚乙二醇二缩水甘油醚(PEGDE)实现了PEDOT∶F的交联,相应小面积柔性器件的效率为14.86%.进一步制备了21.18 cm^(2)的柔性有机光伏模组,其效率达到12.38%.
Silver nanowires(AgNWs)are important printable top electrodes in flexible organic solar cells(OSCs).However,when fabricating AgNWs from ethanol solution,it could cause damage on the hole-transporting layer below due to washing out.In this work,we propose a cross-linking strategy on the hole-transporting layer of poly(3,4-ethylenedioxythiophene)∶perfluorinated sulfonic acid ionomer(PEDOT∶F)to improve its alcohol resistance.By introducing a cross-linker of poly(ethylene glycol)diglycidyl ether(PEGDE),PEDOT:F was successfully cross-linked.Based on the cross-linked PEDOT∶F hole-transporting layer,small-area flexible OSCs(0.041 cm^(2))showed power conversion efficiency of 14.86%.Flexible organic solar module(21.18 cm^(2))was then fabricated and an efficiency of 12.38%was achieved.
