Stable Dye‐Sensitized Solar Cells by Encapsulation of N719‐Sensitized TiO₂ Electrodes Using Surface‐Induced Cross‐Linking Polymerization

Abstract

Encapsulation of a N719-sensitized TiO2 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 JSC and VOC, even with 23% lower N719 coverage relative to the control device.
