A useful Li : A simple reaction between Li 2 O 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.
