Abstract

Here we report a novel transparent conductive oxide (TCO) and Pt free silver nanowire and graphene nanoplatelet (AgNW-GNP) based hybrid counter electrode (CE) for dye-sensitized solar cells (DSSCs) having appreciable photovoltaic performances compared to reference Pt-FTO based DSSCs. Simple solution processed bilayer AgNW-GNP hybrid CEs were prepared to investigate its applicability in DSSCs based on their electrocatalytic and charge transport properties. DSSCs prepared with AgNW-GNP hybrid CEs containing the GNP loading of 0.88 μg/cm2 showed the photoconversion efficiency of 1.61 ± 0.13% which is comparable with that of 1.87 ± 0.15% made of standard Pt-FTO CEs.
