Flame-made tungsten trioxide loaded zinc oxide nanoparticles in hybrid photovoltaic application

WO 3 -loaded ZnO nanoparticles containing 0, 0.25, 0.50, 0.75, 1.0 and 3.0 mol% of WO 3 were synthesized by Flame Spray Pyrolysis (FSP) from zinc naphthenate and tungsten ethoxide precursors under 5/5 (precursor/oxygen) flame condition. The crystalline phase, morphology and size of pure ZnO and WO...
