Abstract

ZnO sphere made of aggregated nanoparticles with a mean diameter of 19 nm have been prepared by the forced thermohydrolysis in polyol medium technique which is a versatile synthesis method for the preparation of metal oxide particles with controlled properties. The sphere were polydisperse and sub-micrometric in size. Porous layers have been prepared using these building blocks. They showed a large specific surface area and were highly light scattering in the visible wavelength region. We have investigated the performances of D149-dyesensitized solar cells (DSSCs) based on these layers. The annealing temperature as well as the layer thickness has been optimized. Finally the best cells reached an overall conversion efficiency of about 4.7% for layers with a thickness ranging between 27 and 35 μm and annealed at 400°C.
