Abstract

In this work, we have studied the photoluminescence (PL) quenching of two polymeric composites, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) and poly(3-hexylthiophene) (P3HT) in presence of nc-TiO$_{2}$ particles by PL- spectroscopy. PL quenching values are 19.2$\text{\%}$ and 45.5$\text{\%}$, for MEH-PPV+nc-TiO$_{2}$ and P3HT+nc-TiO$_{2}$, respectively. The obtained results on the relationship of PL quenching and photoelectrical efficiency (PCE) of an OSC showed that the quenching coefficient of a semiconducting polymer can be considered as apreliminarycriterion for choosing an appropriate polymeric composite being used for OSC preparation. Under illumination of solar energyof 56 mW/cm$^{2}$, P3HT+TiO$_{2}$ based OSC possess FF, V$_{OC}$, J$_{SC}$ and PCE of 0.64, 0.243 V, 1.43 mA/cm$^{2}$ and 0.45$\text{\%}$, respectively.
