METHOD OF MANUFACTURING A LARGE-GRAIN CRYSTALLIZED METAL CHALCOGENIDE FILM, AND A CRYSTALLIZED METAL CHALCOGENIDE FILM PREPARED USING THE METHOD

摘要

The present invention relates to a method for preparing an aqueous or hydro-alcoholic colloidal solution of metal chalcogenide amorphous nanoparticles notably of the Cu₂ZnSnS₄ (CZTS) type and to the obtained colloidal solution.;The present invention also relates to a method for manufacturing a film of large-grain crystallized semi-conducting metal chalcogenide film notably of CZTS obtained from an aqueous or hydro-alcoholic colloidal solution according to the invention, said film being useful as an absorption layer deposited on a substrate applied in a solid photovoltaic device.
