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. date: 2014 type: Article type: PeerReviewed identifier: Tran, Thi Thao and Do, Ngoc Chung and Nguyen, Nang Dinh and Vo, Van Truong (2014) Photoluminescence Quenching of Nanocomposite Materials Used for Organic Solar Cells.
