Abstract

The invention provides a device for single-sided electrolytic treatment of planar substrates. The device comprises: a tank of electrolyte; and a conveying device for conveying a planar substrate along a conveying direction on a free surface of the electrolyte in the tank, wherein the planar substrate is oriented horizontally so that the bottom surface of the planar substrate is aligned with the surface in the tank. The free liquid surfaces of the electrolyte are in contact with each other. The conveying device comprises two conveying elements arranged opposite each other extending along two respective conveying paths, each of which comprises an electrolysis member extending on two opposite longitudinal sides of the tank.

Description

technical field [0001] The invention relates to a device for single-sided electrolytic treatment of planar substrates. Such a planar substrate can be formed not only from a portion of a strip that has been unwound from a reel, but also from discrete plates. Single-sided electrolytic treatment of planar substrates can be used, for example, in the manufacture of solar panels. The invention is especially, but not exclusively, usable with solar cells in which a layer of semiconducting material, generally denoted by the acronym CGIS, is applied to a substrate in the form of a sheet of glass (e.g. 60 cm x 120 cm in size) . The semiconductor material consists of copper, indium, gallium and selenium. [0002] The object of the present invention is to provide a device which makes it possible to carry out the single-sided electrolytic treatment process of planar substrates as efficiently as possible, so that for example solar cells provided with the aforementioned CIGS semiconductor ...
