Improved interface between a layer of material I III vi2 and a substrate of molybdenum

摘要

Improved interface between a layer of material I III vi2 and a substrate of molybdenum, the present invention relates to a method for the manufacture of a thin layer made of an alloy of I - III - VI, and photovoltaic properties.The method according to the invention comprises first steps of: (a) depositing a layer of adaptation (MO) on a substrate (sub), (b) depositing at least one layer (seed) that comprises, at least, the elements I and / or III, in the layer of adaptation.The adaptation layer is deposited under conditions close to vacuum, and the step (b) comprises a first operation of deposition of a first layer of the elements I and / or III, under the same conditions, the deposition of the layer of adaptation, without exposing the layer of adaptation to the air.
