  • Publication number: 20200215509
    Abstract: 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.

  • Patent number: 9391231
    Abstract: The present invention provides a thin compact crystallized layer with large grains of an absorber material essentially consisting of Cu, Zn and Sn sulphide(s), preferably CZTS, with less defects and preferably with improved composition homogeneity and/or reduced content of secondary phases, by producing a method for double annealing, in determined atmospheres, of thin layers of particles of a so-called absorber material based on copper, zinc and tin sulphide, preferably on CZTS, deposited on a substrate covered with molybdenum (Mo), said thin annealed absorber layer deposited on said Mo substrate imparting improved photovoltaic performances to a photovoltaic device which comprises them.
