Dye‐sensitized solar cells (DSSCs) are one type of highly efficient low‐cost solar cells among third‐generation photovoltaic devices. Replacing the expensive components of DSSCs with alternative inexpensive and earth‐abundant materials would further reduce their price in the solar cell market. Recently, graphene‐based low‐cost counter electrodes (CEs) have been developed, which could serve as a potential alternative to the expensive platinum‐based CEs. In this review article, we have summarized recent research on various reduced graphene oxide (rGO)‐based composite CE materials, methods for their synthesis, their catalytic activity, and the effective utilization of such CEs in DSSCs. The photovoltaic performance of DSSCs made of rGO‐based composite CEs were compared with the reference Pt‐based cells, and the photovoltaic parameters are summarized in tables.
