Abstract

New organic semiconducting molecules containing diketopyrrolopyrrole and thiophene units were designed to investigate the influence of effective conjugation length on the performance of organic photovoltaics made with [6,6]-phenyl-C61-butyric acid methyl ester. New D-A-D-A-D type molecules (where; D = donor, A = acceptor) such as ter- and quarter-thiophene bridged diketopyrrolopyrrole dimers were synthesized with different numbers of conjugative units. The field-effect mobilities of these molecules were determined by fabricating thin film transistors. The new molecules displayed moderately high mobility between 3.6 × 10^-2 and 1.1 × 10^-2 cm² V^-1 s^-1 without a thermal annealing process for TT(BTDPP)₂ and QT(BTDPP)₂. The TT(BTDPP)₂ molecule possesses a longer effective conjugation length (c.f. QT(BTDPP)₂) and shows a high carrier mobility. When employing the ter- and quarter-thiophene bridged diketopyrrolopyrrole dimers as donor molecule in combination with [6,6]-phenyl-C61-butyric acid methyl ester [TT(BTDPP)₂:PC₆₁BM = 1:0.8 w/w], the photovoltaic cell provides the highest power conversion efficiency of 3.76%.
