Development of liquid crystal embedded in polymer electrolytes composedof click polymers for dye-sensitized solar cell applications

Two different methods were used to synthesizefluorene-based click polymers, and their effects on theirphotovoltaic performance in dye-sensitized solar cells were compared. The dye-sensitized solar cells witha configuration of SnO2:F/TiO2/N719 dye/polymer electrolyte/Pt devices were fabricated using these clickpolymers as the electrolyte components. We also compared the photovoltaic performance of these liquidcrystal embedded in click polymers to that of poly(acrylonitrile). Among the devices, the device composedof the CuI-catalyzed click polymer exhibited high power conversion efficiency of 4.70% at 1 sun, which wasas high as that of the poly(acrylonitrile)-composed polymer electrolyte.
