The present invention provides PHPIT and fabrication thereof. PHPIT has a side-chain-tethered with hexylphenanthrenyl-imidazole polythiophene. The visible light absorption of the PHPIT/PCBM blend is enhanced by the presence of the electron-withdrawing hexylphenanthrenyl-imidazole. The PHPIT/PCBM blend experienced more-balanced electron and hole mobilities and solvability.

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.
