Title: Solid material in the divided state, process for the production of such a material, and use of such a material in a photovoltaic cell

Abstract: The invention relates to a solid material with the following formula (A): (Cu.sup.+1.sub.a-u; Ag.sup.+1.sub.u; Zn.sup.+2.sub.b-v-(y/2); Cd.sup.+2.sub.v; Sn.sup.+4.sub.c-w-(y/2); .sup.1X.sup.+4.sub.w; .sup.2X.sup.+3.sub.y; S.sup.-2.sub.x)(A), in which the solid material: is in divided state in the form of particles having a mean equivalent diameter of 15 nm to 400 nm; has, according to X-ray diffraction analysis of the solid material, a unique crystalline structure; is suitable for forming a stable dispersion of at least one solid material with formula (A) in a liquid, referred to as dispersion liquid, made up of at least one compound with a value of .delta..sub.p higher than 8 and a value of .delta..sub.H higher than 5.
