A dye-sensitized solar cell comprising a photo electrode, a counter electrode , a sensitizer and an electrolyte layer . The photo electrode includes a compact semiconductor layer and a porous semiconductor layer . The compact semiconductor layer and the poroussemiconductor layer are disposed on a conducting glass. Further, the sensitizer is coupled to the porous semiconductor layer and the electrolyte layer is disposed between the photo electrode and the counter electrode. Furthermore, the electrolyte layer contains a primarypolymer host and asecondarypolymer host, at least two non-volatile polymer solvents and a redox couple.More particularly, the primary polymer host is phthaloyl chitosan.
