Patent ID: 8114315

Claim:
A method for fabricating organic polymer of solar cell, comprising: reacting 3,6-dibromophenanthrene-9,10-dione with 3-thiophenecarboxaldehyde, 4-hexylaniline, ammonium acetate and acetic acid to form as a Compound 1; reacting the Compound 1 with hexyl magnesium bromide and Ni(dppp)Cl 2 to form as a Compound 2; reacting the Compound 2 with N-bromosuccinimide (NBS), tetrahydrofuran (THF), and acetic acid to form a 2-(2,5-dibromothiophen-3-yl)-6,9-dihexyl -1-(4-hexylphenyl)-1H-phenanthro[9,10-d]-imidazole (HPIT); and reacting the HPIT with tetrahydrofuran, methyl magnesium bromide and Ni(dppp)Cl 2 to form the organic polymer of solar cell.
