Encapsulation of a N719‐sensitized TiO 2 electrode is successfully achieved through surface‐induced cross‐linking polymerization of a coadsorbent, which forms a robust, network polymer film. Dye‐ sensitized solar cells with the film exhibit a remarkable long‐term stability (>95% of the initial activity after 480 h) with simultaneous improvement in J SC and V OC , even with 23% lower N719 coverage relative to the control device.
