Soluble phenanthrenyl imidazole for photo-electrical conversion of solar cell

Abstract

A novel material of phenanthrenyl imidazole is applied to a solar cell. A phenanthrenyl-imidazole moiety is introduced to reduce a power band of a polymer, so that a photocurrent and an optoelectrical transformation efficiency are improved. Thus, a polymer having the novel material is very suitable to be used in a solar cell to acquire a high optoelectrical transformation efficiency.
