Process for covering a transparent conductive oxide layer with a continuous layer of conductive material chosen from silver, copper, gold, aluminium and mixtures thereof, comprising at least the steps consisting in: (i) providing a transparent conductive oxide layer; (ii) forming, at the surface of said layer, a plurality of clusters of material via the following consecutive steps: (a) depositing evenly distributed drops on said surface, the spacing between two neighbouring drops being adjusted so that the drops do not coalesce on spreading; said drops being formed of a liquid medium comprising a material in one or more solvents, and having a good wettability with respect to the transparent conductive oxide of the lower layer and with respect to the conductive material intended to form the continuous upper layer; a good wettability of said liquid medium with respect to a given material being understood to mean having a contact angle, of a drop of said liquid medium deposited on a support made of said material, of strictly less than 90°; and (b) evaporating said solvent(s) contained in the drops deposited in order to form said clusters of material; the degree of coverage of the surface of said transparent conductive oxide layer by said clusters of material being adjusted in order to guarantee the formation of a continuous upper layer made of conductive material; and (iii) forming, on the surface of the assembly obtained at the end of step (ii), said desired layer of conductive material.
