Most of the dye‐sensitized solar cells (DSSCs) developed so far use organic electrolytes and water‐sensible sensitizers. The search for aqueous DSSCs, a promising technology for solar‐energy conversion, implies finding materials that are stable in aqueous solution. In this study, Prussian blue (PB) was utilized as an innovative sensitizer in a photoanode for DSSCs and a novel synthetic approach to a carbon nanotubes/TiO 2 /PB nanocomposite thin film was developed. The photoresponse was evaluated in a total aqueous electrolyte, and photocurrents of 600 μA cm −2 were achieved.
