✦ Synopsis

Abstract

Poly(propylene carbonate) (PPC) is synthesized from the copolymerization of CO~2~ and propylene oxide. Novel nanocomposite gel polymer electrolytes (GPEs) are prepared by utilizing PPC, organic solvents containing a redox couple, and aluminum oxide nanoparticles for application in dye‐sensitized solar cells (DSSCs). The quasi‐solid‐state DSSC assembled with optimized nanocomposite GPEs exhibits a relatively high conversion efficiency of 6.16% at 100 mW cm^−2^ and better stability than DSSC with liquid electrolyte.
