Abstract
The invention relates to manufacturing a I-III-VI compound in the form of a thin film for use in photovoltaics, including the steps of: a) electrodepositing a thin-film structure, consisting of I and/or III elements, onto the surface of an electrode that forms a substrate (SUB); and b) incorporating at least one VI element into the structure so as to obtain the I-III-VI compound. According to the invention, the electrodeposition step comprises checking that the uniformity of the thickness of the thin film varies by no more than 3% over the entire surface of the substrate receiving the deposition.
