ABSTRACT:
A polymer electrolyte for dye sensitized solar cell is provided. The electrolyte contains a porous hybrid polymer (the components were listed in formula (1) and formula (2)) and the electrolyte solution (the components were shown in formula (3)).The weight ratio of PEOPPO to PVDF-HFP is from 1˜80%The weight ratio of EO to PO in PEOPPO is from 30 to 80%in-line-formulae description="In-line Formulae" end="lead"?EC/PC/LiI/I2/TBP  Formula (3)in-line-formulae description="In-line Formulae" end="tail"?EC is ethylene carbonatePC is propylene carbonateTBP is 4-tert-butylpyridineThe weight ratio of EC to PC is 0.1˜5; the ratio of EC to LiI is 0.1˜2; the ratio of EC to I2is 0.01˜0.2; the ratio of EC to TBP is 0.1˜1;wherein the range of n and m for PEOPPO is n=20˜150, and m=10˜80.
