Improving performance requires a firm understanding of how to optimize both material composition and processing parameters. In this thesis, we examine processing parameters that include solution composition, annealing temperature, and the rates of spin casting and evaporative coating. We also find that the optimal weight ratio for the active layer of a ZnO:P3HT solar cell is 40 wt. % ZnO.application/pdfengHybrid solar cellOrganic photovoltaicsZinc oxide nanoparticlesPoly(3-hexylthiophene)Solar cellsthesis2011-02-16
