Mesoporous NiO films obtained via screen-printing deposition of a newly formulated paste containing preformed NiO-nanospheres have been employed as nanostructured photocathodes of p-type dye-sensitized solar cells (p-DSCs).
Nanotechnology mainly consists of the processing, separation, consolidation, and deformation of materials by one atom or by one molecule. It is an applied research of materials and devices operated at nanometer scale.
