A method for preparing an A-B-C2 or A2-(Dx, E1—x)-C4 absorber thin film for photovoltaic cells where 0≦̸x≦̸1, A is an element or mixture of elements selected within Group 11, B is an element or mixture of elements selected within Group 13, C is an element or mixture of elements selected within Group 16, D is an element or mixture of elements selected within Group 12, and E is an element or mixture of elements selected within Group 14. Said method includes: a step of electrochemically depositing oxide from elements selected from among Groups 11, 12, 13, and 14, a step of annealing in a reducing atmosphere, and a step of supplying an element from Group 16.
摘要:
A method and device for electrodeposition in cylindrical geometry. The invention relates to a method for electrochemically depositing a thin layer on a flexible substrate, comprising the following steps: -providing, in an electrolysis bath, a first closed cylinder in a second hollow cylinder, -applying the flexible substrate to one of the surfaces chosen from the outer surface of the first cylinder and the inner surface of the second cylinder, the flexible substrate forming a first electrode, -providing, in the electrolysis bath, a second electrode, and -applying a potential difference between the first electrode and the second electrode in order to electrodeposit the thin layer on the flexible substrate.
