Abstract

A composite catalyst of rosin carbon/Fe₃O₄ with marvellous morphology was synthesized and applied as a counter electrode (CE) in dye-sensitized solar cells (DSCs), demonstrating notable electrocatalytic activity for the reduction of I₃⁻. Based on this CE, a high power conversion efficiency of 8.11% was achieved, comparable to that of the traditional Pt CE.
