Paper Abstract

Photoluminescence (PL) and photovoltaic (PV) performance of poly3-octylthiophene (P3OT) and poly3-alkylthiophene (P3DT) were studied in detailed. The two kinds of polymer can exhibit strong deep red emission peaking at 688 nm for P3OT and 675 nm for P3DT under blue light excitation, the effective excitation wavelength is about 462 nm. The dynamic process of exciton induced by light excitation strongly determined the PL and PV characteristics. From the PL excitation spectra of P3OT and P3DT, it can be seen that there are wide and intense excitation wavelengths in the visible light range. Two kinds of polymer solar cells based on P3OT or P3DT doping with PCBM were fabricated and the characteristics of OPVs were measured, the short current density (Jsc) and open circuit voltage (Voc) are 0.84 mA/cm2, 0.95 mA/cm2 and 180 mV, 270 mV, respectively.
