▎ 摘　　要

Graphene-based nanomaterials functionalized by different doping strategies have attracted great attention for energy conversion themes, due to their large specific surface area, high conductivity, and appreciable electrocatalytic properties. This mini-review presents an overview of the recent progress in the synthesis of graphene-based nanomaterials as counter electrodes for dye-sensitized solar cells based on iodine/iodide electrolytes, along with challenges and perspectives in this exciting field.
