Abstract
Dye sensitized solar cells (DSSCs) solid-state electrolytes were prepared by mixtures method and applied to dye sensitized solar cells (DSSCs). The cells were coated a conducting glass sheet by means of doctor blade technique. The solid state electrolytes were prepared by adding KI and I2 into solid state electrolytes composed of 1,2,4,5- tetrakisbromomethyl benzene(TB), γ-butyrolactone (GBL), propylene carbonate(PC), 1-methyl-3-propylimidazodium iodide (MPI), poly (styrene-co-acrylonitrile)(P(S-A)) and ethylene carbonate (EC). The solid state electrolytes mixtures became homogenous and could not flow under sintering at temperature of 70-80°C gelated with sample 1, 2, 3 and 4. The dye sensitized solar cells (DSSCs) based on the solid state electrolytes yielded an overall light to electrical energy conversion efficiency of 2.49%, 2.56%, 2.16% and 2.18% respectively, under irradiation of 80 mW/cm2.
