Abstract
A new low-band gap polymer containing thiophene and cyclopentadiene, poly(5,2,2'-dioctyldithiophenylcyclopentadiene) (PDTCP), has been synthesized via the FeCl3 oxidative polymerization. PDTCP showed a broad absorption band and a low energy band gap of 1.82 eV. The photoluminescence (PL) of PDTCP is completely quenched upon addition of PCBM indicative of efficient charge transfer. Bulk heterojunction organic photovoltaic cells (OPVs) fabricated from PDTCP as an electron donor showed an open-circuit voltage (VOC) of 0.50 V, a short-circuit current (JSC) of 1.24 mA/cm 2, and the power conversion efficiency of up to 0.20% under AM 1.5 (100 mW/cm 2).
