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...

Zusammenfassung:	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. •Liquid crystal has been improved the crystallinity of the poly(3-hexylthiophene) layer.•Efficiency of bilayer solar cell has been increased with liquid crystal.•Significant improvements have been achieved by using liquid crystal additive.
