Fullerene functionalized polystyrene (PSFu) with a variety of fullerene (C-60) contents was synthesized and characterized. The best PSFu was selected on the basis of solubility and band gap energy for application studies. Feasibility for using PSFu as a replacement of C-60 in bulk heterojunction (BHJ) polymer solar cells was explored. Performance of the BHJ cells containing PSFu was comparable to that of the cells containing neat C-60, irrespective of the acceptor/donor weight ratios, even the actual amount of C-60 in PSFu molecules was (about 5 times) lower than that of the neat C-60.
