Dye-sensitized solar cells containing polymer film with honey-comb like morphology

Flat membranes with honey-comb like morphology were prepared on dye coated TiO2 electrode. Liquid electrolytes were immobilized in the pores of the honey-comb like structure of the polymer membranes due to high capillary force. The liquid impregnated polymer membranes were introduced to dye-sensitized solar cells (DSSCs), forming quasi-solid-state electrolytes for highly efficient DSSCs with an overall energy-conversion efficiency of ∼8% at room temperature under 1 sun illumination.
