Study of Some Structural and Optical Properties for P3HT: CBM Heterojunctions Blending of ZnS Nanoparticles

Abstract

Abstract In this work, the preparation of P3HT: PCBM heterojunction blending ZnS nanoparticles (NPs) was demonstrated. Some structural and optical properties of the hybrid structure films were presented. ZnS NPs films were prepared by chemical route method and at different pH values. Then, the nanoparticles ZnS was incorporated in P3HT : PCBM solution in chlorobenzene with the weight ratios of 0, 5, 10 and 15 wt %. The X-ray diffraction patterns of the ZnS nanoparticles films and SEM images of the hybrid structure films are discussed. Also, the absorption spectra in the range of 200-1100 nm of the blends for variable weight ratios samples and the effect of ZnS pH values on these spectra are presented.
