• high-molecular-weight PEO copolymers

Low-crystalline random and gradient P(EO-co-PO) copolymers and amorphous PPO and PBO of high molecular weight were synthesized by anionic coordination polymerization. Polymer gel electrolytes based on these (co)polymers were prepared and tested for long-term performance of DSSC. The DSSC based on P(EO-co-PO) copolymers have longer life time compared to the homo-PEO- and homo-PPO-based DSSC, respectively. The cells containing the chemically crosslinked copolymer gel exhibited a high efficiency of 6% after 25 d performance, whereas the solar cells based on physically crosslinked copolymer gel showed fast degradation.
