摘要

Organic solar cells(OSCs)have attracted much attention due to their advantages in fabricating flexible and semi-transparent devices.Especially,the light weight,flexibility and spectral adjustability make OSCs superior to silicon,perovskite and other thin film based solar cells in applications of inte-grated photovoltaic devices and wearable electronics.In flexible and semi-transparent OSCs,transparent conducting electrodes(TCEs)play a key role in obtaining high performances.Among various TCEs,silver nanowire(AgNW)has become a promising candidate due to its low sheet resistance,high optical transparency,excellent mechanical flexibility and solution processability.In this article,we review the recent advances in AgNW-based TCEs and their applications in the field of OSCs.Firstly,we introduce the general properties of AgNW,including optoelectronic and mechanical characteris-tics.Secondly,the preparation methods of AgNW are discussed,along with some approaches on the optimization of AgNW to overcome the short-comings of TCEs.Thirdly,we discuss the applications of AgNW as TCEs in fabricating flexible and semi-transparent OSCs,including the use of AgNW as bottom and top electrodes.Finally,we point out the challenges in AgNW-based TCEs and suggest several guidelines for preparing AgNW so as to meet the demands for the practical use of OSCs.
