제목 A synthetic approach to a fullerene-rich dendron and its linear polymer and performance of the solar cells
초록 Through the esterification of an acyl chloride functionalized fullerene precursor with dendritic alcohol, a fullerene-rich dendron containing a norbornene unit at the focal point is prepared for ring-opening metathesis polymerization to obtain its linear polymer with a unimodal and narrow molar mass distribution (PDI = 1.08) by a progressive addition of catalysts. Moreover the potential applications of these dendritic-type fullerenes in organic photovoltaic devices(OPVs), the active layers in bulk heterojunction OPVs were fabricated with P3HT. The weight ratio of P3HT to fullerene-rich dendron was 1 : 1, whereas in the case of fullerenerich linear polymer the ratio was 1 : 0.5. The photovoltaic performance based on fullerenerich dendron shows a Jsc of 5.23 mA cm-2, a Voc of 0.50 V, a fill factor (FF) of 0.52 and PCE of 1.36%. The device using fullerene-rich linear polymer delivers performance with a Jsc of 3.61 mA cm-2, a Voc of 0.44 V, a FF of 0.33, decreasing the PCE to 0.52%.
