The following soluble π-conjugated polymer was synthesized by palladium-catalyzed Suzuki polymerization: poly[(9,9-dioctylfluorene)-alt-(3- hexylthiophen-5-yl)-(4'-hexylthiazol-5'-yl)] poly(FO-HThHTha) derived from poly(9,9-dioctylfluorene) (PFO) and poly[(3-hexylthiophen-5-yl)-2,2'-(4'- hexylthiazol-5'-yl)] poly(HThHTa). The polymer, poly(FO-HThHTa) was soluble in common organic solvents and easily spin coated onto indium-tin oxide (ITO) coated glass substrates. Bulk heterojunction photovoltaic cells with an ITO/PEDOT/poly(FO-HThHTa):PC70BM/TiOx/Al configuration were fabricated and the photovoltaic cell using poly(FO-HThHTa):PC 70BM (1:4) showed the best photovoltaic performance compared with those using poly(FO-HThHTa):PC70BM (1:2 and 1:6). The optimal bulk heterojunction photovoltaic cell exhibits a power conversion efficiency (PCE) of 0.39% (Voc=0.44 V, Jsc=2.57, FF = 0.34) with poly(FO-HThHTa):PC70BM (1:4) measured by using an AM 1.5G irradiation (100mW/cm2) on an Oriel Xenon solar simulator (Oriel 300W).
