Quasi-solid-state nanocrystalline TiO 2 solar cells using gel network polymer electrolytes based on polysiloxanes

A quasi-solid-state dye-sensitized nanocrystalline porous TiO 2 film solar cell was fabricated using a novel gel network polymer electrolyte based on polysiloxanes with both polyethylene oxide internal plasticized side chains and quaternary ammonium groups. The cell exhibited better photoelectrical conversion performance under 60 mW/cm 2 irradiation. The short photocurrent ( I sc ) of 5.0 mA/cm 2 and open voltage ( V oc ) of 0.68 V were achieved, and the energy conversion efficiency (η) and fill factor (ff) were 3.4% and 0.60, respectively.
