This research work has concern a synthesis and application of donor-acceptor block copolymer, namely poly (3-hexyl thiophene)-b-fullerene grafted polystyrene, in bulk heterojunction polymer solar cell based on P3HT/C60 system. The primary aim of this work is to explore a feasibility for using the above block copolymer as a compatibilizer for controlling morphology and enhancing power conversion efficiency of the solar cell. The block copolymer was firstly prepared by synthesizing the P3HT macrointiator via a multiple synthetic route, in accordance with the methods described in literatures. After that, the macroinitiator was further reacted with styrene and chloromethyl:styrene via an ATRP mechanism. Finally, the above copolymer was functionalized with fullerene via an ATRA mechanism to obtain the donor-acceptor block copolymer. Chemical structures, molecular weight and thermal properties of the prepared block copolymer was confirmed by using FTIR, 1H-NMR, TGA, and UV-Visible spectroscopy technique. Next, the polymer solar cells were fabricated by coating P3HT/C60 onto ITO glass, using a spin coating technique. Au electrode was then coated on top of the active layer, using a thermal evaporator. From the results, it was found that power conversion efficiency (PCE) of the normal cell (P3HT/C60) is 0.02 %. However by adding the prepared block copolymer, PCE of the cell increased to 0.23 %.
