The influence of ZnS quantum dots (QDs) on the photo-physical and electrical properties of poly(3-hexylthiophene) (P3HT) conjugated polymer, has been investigated. Composite material has been prepared by blending P3HT with low concentration of chemically synthesized ZnS nanocrystals. Absorption spectra of conjugated polymer exhibit a small blue shift of about 3 nm, with the incorporation of ZnS nanocrystals. We observed the charge transfer between conjugated polymer molecules and ZnS nanoparticles which is discussed with the energy levels of the materials. Current density–voltage measurement of the hybrid device showed a significant improvement in Voc in comparison to P3HT only device.
