PRODUCTION OF THIN FILMS HAVING PHOTOVOLTAIC PROPERTIES AND CONTAINING A I-III-VI₂-TYPEALLOY, COMPRISING SUCCESSIVE ELECTRODEPOSITS AND THERMAL POST-TREATMENT

摘要

The invention relates to the production of a thin film having photovoltaic properties, containing a I-III-VI₂-type alloy and deposited by electrolysis, including the following steps: (a) successive deposits of layers of metallic elements I and III; and (b) thermal post-treatment with the addition of element VI. In particular, step (a) comprises the following operations: (a1) depositing a multi-layer structure comprising at least two layers of element I and two layers of element III, deposited in an alternate manner; and (a2) annealing said structure before adding element VI in order to obtain a I-III alloy.
