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 cm2的柔性有机光伏模组, 其效率达到12.38%.

Abstract:

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 cm2) showed power conversion efficiency of 14.86%. Flexible organic solar module(21.18 cm2) was then fabricated and an efficiency of 12.38% was achieved.

Key words: Hole-transporting layer, PEDOT∶F, Cross-linking, Silver nanowires, Flexible organic solar cell
