METHOD FOR REGENERATION OF AN ELECTROLYSIS BATH FOR THE PRODUCTION OF A COMPOUND I-III-VI2 IN THIN LAYERS

摘要

The invention relates to the regeneration of an electrolysis bath for the production of I-III-VIY compounds in thin layers, where y is approaching 2 and VI is an element including selenium, whereby selenium is regenerated in the form Se(IV) and/or with addition of oxygenated water to reoxidise the selenium in the bath to give the form Se(IV).
