Abstract
The invention relates to a method for preparing a colloidal nanoparticle solution, including: (a) dissolving a titanium-oxide precursor, referred to as a precursor, in one or more solvents, referred to as precursor solvents; and (b) chemically converting, preferably by means of hydrolysis, said titanium-oxide precursor and said precursor solvent into a colloidal-solution solvent so as to form titanium-oxide nanoparticles that are dispersed in the colloidal-solution solvent, said colloidal solution having a dynamic viscosity of between 4 and 54 cP at 20° C. and 101,325 Pa. The invention also relates to a colloidal titanium-oxide nanoparticle solution containing a dispersion of titanium-oxide nanoparticles in a solvent or system of solvents, the viscosity of which is between 4 and 54 cP, said solution being particularly obtainable according to the method of the invention, as well as to the uses thereof, in particular for preparing photovoltaic cells. The invention also relates to a method for generating power using a semiconductor prepared from said solution.
