This work presents a facile route for fabricating bimetallic (tungsten and molybdenum)-reduced graphene oxide nanocomposites as a promising electrocatalyst for dye-sensitized solar cells. The properties of the nanocomposites were investigated using various characterization tools, and their photovoltaic and electrochemical performance were evaluated. The bimetallic nanocomposites exhibited comparable power conversion efficiency to traditional materials and could be a feasible alternative with reduced production cost.
This work outlines the facile route of fabricating bimetallic (tungsten and molybdenum)-reduced graphene oxide (rGO) nanocomposites (GWMo) as an electrocatalyst for use of counter electrodes in dye-sensitized solar cells (DSSCs). Systematic investigations were carried out to determine their properties using various characterization tools. The photovoltaic and electrochemical performance of the bimetallic nanocomposites were investigated using the J-V characteristics and cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and Bode-plot, respectively. The well-grounded electrocatalytic performance of the as-prepared GWMo nanocomposites provides a feasible alternative to rare earth elements (i.e. platinum) and potentially reduces the production cost of cells (DSSCs). The catalytic activity and electrical conductivity of the GWMo nanocomposites exhibit a comparable power conversion efficiency (eta) of similar to 4.28%.
