Template-free synthesis of closed-microporous hybrid and its application in quasi-solid-state dye-sensitized solar cells

Abstract

A kind of closed-microporous hybrid with poly(acrylic acid)-poly(ethylene glycol)-polypyrrole (PAA-PEG-PPy) was synthesized template-free by in situ polymerization and micro-phase separation of PPy in PAA-PEG gel. This novel structure hybrid was used as a matrix in preparing polymer gel electrolytes for quasi-solid-state dye-sensitized solar cells (QS-DSSC). It shows high liquid electrolyte absorbency and salt tolerance, which are benefits for improving photovoltaic performance of QS-DSSC.
