The photoactive materials in dye‐sensitized solar cells (DSSCs) are conventionally produced by colloid coating and heat treatment followed by dye adsorption by dipping in solution. One disadvantage of this procedure is that only heat‐resistant materials can be used. Here the one‐step self‐assembly of ZnO/eosin Y thin films is reported. It is shown that a large proportion of the incorporated eosin Y dye molecules act as sensitizers, making the films suitable as sensitized photoelectrodes in DSSCs. No heat treatment is required, allowing non‐heat‐resistant substrates such as flexible conductive plastic films to be used.
