Carbonized Eggshell Membranes as a Natural and Abundant Counter Electrode for Efficient Dye‐Sensitized Solar Cells

Abstract

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.
