N2  - 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-TiO2 particles by PL- spectroscopy. PL quenching values are 19.2\% and 45.5\%, for MEH-PPV+nc-TiO2 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/cm2, P3HT+TiO2 based OSC possess FF, V$_{OC}$, J$_{SC}$ and PCE of 0.64, 0.243 V, 1.43 mA/cm2 and 0.45\%, respectively.
