Deiodized salt: An organic redox couple (McMT−/BMT) was adopted for application in dye‐sensitized solarcells. Based on a low‐cost organicdye, TH305, an efficiency of 4.0 % was achieved under simulated sunlight (100 mW cm−2). Photoelectrochemical measurements provided insights into the difference between the organic redox couple and traditional iodine‐basedelectrolytes.
