A method for the wet chemical synthesizing dicopper - zinc - tin - tetrasulfide and / or - tetra selenide (czts), a method for producing a semiconductor layer of czts as well as a colloidal suspension

摘要

The invention relates to a method for the wet chemical synthesizing dicopper - zinc - tin - tetrasulfide and / or - tetra selenide (czts) semiconductors - nanocrystallites. Thus a semiconductor layer of the czts - material is a correct stoichiometry and a good crystal structure and the czts - material, in particular for producing a solar cell, lighter and more effective can be applied to a carrier material, the method according to the invention is characterized in that a mixture of a solvent and at least in each case of a copper -, zinc - and tin - connection is produced and a selenization by means of at least one compound containing selenium and / or a sulfidation by means of at least one sulfur compound is carried out.
