▎ 摘 要
This work reports on dye-sensitized solar cells (DSSCs) with an electroplated graphene electron transport layer. The induced electroplating graphene layer in the DSSC structure substantially improves the performance of the DSSCs because the electroplated graphene exhibits superior conductivity and a favorable work function (4.8 eV) between that of the TiO2 photoanode and that of the ITO conductive layer. The short-circuit current density and the power conversion efficiency of the control sample without graphene are 4.43 mA/cm(2) and 1.39%, respectively, whereas those of the DSSC that was electroplated with graphene for 20 min are 11.8 mA/cm(2) and 3.41%, respectively. The improvement in the open-circuit current and the power conversion efficiency is attributable to electron transport. (C) 2015 Elsevier Ltd. All rights reserved.
