A method and device for electrodeposition in cylindrical geometry. A method for electrochemically depositing a thin layer on a flexible substrate, comprising: 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, 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.

Method and device for electroplating in cylindrical geometry

A method for preparing an A-B-Cor A-(D,E)-Cabsorber thin film for photovoltaic cells where 0&#x2266;x&#x2266;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.
