چکیده انگلیسی
A conjugated polymer, poly(3-hexyl-2,5-diphenylthiophene)-p-bisdodecyloxy-phenylene vinylene) (CP) was synthesized whose chemical structure was confirmed by 1H-NMR and FTIR. CP possesses electrochemical band gap of 2.19Â eV, determined by cyclic voltammetry (CV), and low laying highest occupied molecular orbital (HOMO) energy level (5.24Â eV). Acting as an electron donor, CP was mixed with electron acceptor PC61BM in (1:1, w/w) to fabricate the photoactive layer. The resultant CP:PC61BM (1:1, w/w) based polymer solar cell (PSC) under AM 1.5G (100Â mWcmâ 2) showed power conversion efficiency (PCE) of 2.66% with an open-circuit voltage (VOC) of 678Â mV, a short circuit current density (JSC) of 7.711Â mA/cm2 and a fill factor (FF) of 50%. Band gap of CP calculated by Density functional theory (DFT) measurement was determined to 2.04Â eV, which was in good agreement with the experimental value obtained by CV.
