Polyaniline/ZnO hybrid nanocomposite: Morphology, spectroscopy and optimization of ZnO concentration for photovoltaic applications

The appropriate combination of semiconducting polymer-inorganic nanocomposites can enhance the existing performance of polymers-only-based photovoltaic devices. Hence, polyaniline (PANI)/zinc oxide (ZnO) nanocomposites were prepared by combining ZnO nanoparticles with PANI in four distinct ratios to...
