3D Honeycomb‐Like Structured Graphene and Its High Efficiency as a Counter‐Electrode Catalyst for Dye‐Sensitized Solar Cells

Abstract

A useful Li: A simple reaction between Li2O and CO, gives a new type of three-dimensional graphene sheets—honeycomb-structured graphene. A dye-sensitized solar cell (DSSC) with the new graphene counter electrode has an energy conversion efficiency as high as 7.8 %, which is comparable to that of DSSCs with an expensive Pt counter electrode.
