Bilayer polymer/fullerene solar cells with a liquid crystal

In this paper the effect of 5-(10-undecenyloxy)-2-[[[4-hexylphenyl]imino]methyl]phenol liquid crystal addition into poly(3-hexylthiophene):fullerene containing solar cells were investigated. Based on current-voltage characteristics, we report on the efficiency enhancement for bilayer heterojunction solar cells using this liquid crystal.
