Abstract
We report for the first time an in situ photopolymerization of model co‐monomers, 2‐hydroxyethyl methacrylate (HEMA) and tetra (ethylene glycol) diacrylate (TEGDA), in an IL electrolyte containing I~2~ for DSSCs. TiO~2~ nanoparticles were used as the photo‐initiator and co‐gelator in a charge transfer polymerization reaction. The gel‐IL polymer obtained was characterized in terms of the diffusion properties of the electrolyte. Preliminary results from DSSCs assembled using the gel‐IL electrolyte showed energy conversion efficiency of 3.9% at 1 sun (AM1.5) and 5.0% at 0.39 sun illumination.
