Effective cationic dye‐sensitized nanocrystalline titania solar cells employing an elastomeric copolymer of ethylene glycol and epichlorohydrin as electrolyte and I – /I 3 – as mobile redox carrier system have been developed by these authors. The key feature of the copolymer is its ability to penetrate the pores of the TiO 2 film in spite of its high molecular weight. Unsealed prototype cells show 1.6–2.6 % energy conversion efficiency, thus demonstrating that polymer electrolytes are an attractive alternative to previously reported hole‐transporting materials.
