A low‐cost, sulfur‐doped NiO (S–NiO) thin film is electrodeposited on fluorine‐doped SnO 2 substrate and studied in an iodide‐based redox system. High electrochemical activity is present because of a large catalytic surface area and a low charge transfer resistance. A dye‐ sensitized solar cell with a low‐loaded S–NiO counter electrode achieves a power conversion efficiency of 5.04%, close to that of a cell with a conventional platinized electrode.
