Abstract Dye‐sensitized solar cells (DSSCs) have become a strong reality in the field of hybrid photovoltaics. Their ability to operate diffused light conditions and possibility fabrication modules bearing different colors make these attractive for applications, example, wearable electronics, building integration, etc. This review focuses on one compounds rather often studied DSSCs, namely, poly(3,4‐ethylenedioxythiophene) (PEDOT). It has been introduced both as substitute liquid electrolytes, order facilitate increase their durability, an alternative platinum counter electrodes. The literature counts many studies PEDOT this manuscript collects them following classification criterion based functionalization/doping strategies, deposition methods. In addition comparing performance obtained PEDOT‐based systems with those traditional (i.e., assembled iodine‐based electrolytes cathodes), also offers brief analysis costs sustainability aspects, built up experimental data found literature; latter is expected constitute precious resource catalyze attention scientific community relevant preliminary aspects when figuring out industrial scalability newly proposed cell components.
