A promising, natural, and abundant eggshell‐membrane‐derived counter electrode for dye‐sensitized solar cells is presented. The carbonized sucrose‐coated eggshell membranes consist of unique micropores of less than 2 nm, which effectively catalyze the triiodide into iodide in the light–electricity conversion process, leading to an improvement in the open‐circuit voltage ( V oc ) and a competitive conversion efficiency.
