▎ 摘　　要

NOVELTY - Producing dye-sensitized solar cell, comprises (a) forming a polymer particle layer on a counter electrode, (b) coating graphene flakes on the polymer particle layer, and (c) injecting an electrolyte in a gap between the counter electrode and a photo electrode to form a polymer matrix by in-situ gelation of the polymer particle layer by electrolyte solution containing solvent, and dispersing graphene flakes in the polymer matrix to form a polymer/graphene composite gel electrolyte. USE - The method is useful for producing dye-sensitized solar cell (claimed). ADVANTAGE - The dye-sensitized solar cell has excellent compatibility and conductivity, and improved photoelectric conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for dye-sensitized solar cell comprising polymer/graphene composite gel electrolyte containing graphene flakes dispersed in polymer matrix.
