Abstract

We report the chemical synthesis of various ZnO nanostructures and TiO ₂ nanoparticles and their dispersion in a P3HT matrix. The photoluminescence studies revealed improved charge transport in the active layer of the optimized TiO ₂ nanoparticles at a wt. ratio of 0.33, which demonstrated enhanced effective exciton dissociation at the interfaces between the P3HT, ZnO and TiO ₂ domains. The influence of the synthesis reaction time for the various ZnO nanostructures and TiO ₂ nanoparticles on the solar cell performances was investigated by varying the TiO ₂ concentration. The device containing a 0.33 wt. ratio of TiO ₂ nanoparticles in ITO/SnO ₂ /P3HT:ZnO(24-h):TiO ₂ /MoO ₃ /Al ternary system showed a maximum efficiency of 2.84% under AM 1.5G illumination.
