An electrolyte for a dye-sensitized solar cell is disclosed. The electrolyte includes a solvent being one selected from a group consisting of gamma-butyrolactone (gBL), propylene carbonate (PC) and 3-methoxypropionitrile (MPN), and a polymer mixed with the solvent to form an electrolyte solution, wherein when the solvent is one of gBL and PC, the polymer is one selected from a group consisting of polyacrylonitrile (PAN), polyvinyl acetate (PVA), poly(acrylonitrile-co-vinyl acetate) (PAN-VA) and a combination thereof; and when the solvent is MPN, the polymer includes one of a mixture of poly(ethylene oxide (PEO) and polyvinylidene fluoride (PVDF), and a mixture of PEO and polymethylmethacrylate (PMMA).
