Latent gel electrolyte precursors for quasi-solid dye sensitized solar cells

New latent chemically-cross-linked gel electrolyte precursors for quasi-solid dye sensitized solar cells (QDSC) are reported. The gel electrolyte precursors consist of nano-particles and dicarboxylic acids as the latent gelators. The viscosity of the precursor is low at first and does not increase during storage at room temperature. However, when the precursor is baked at 80 degrees C, it solidifies immediately. Photo-voltaic performance is maintained after solidification.
