Application No. / Patent No.: 200 580 014 778
Provide a chalcopyrite-type thin film solar cell production methods, the electrode layer and from yellow to copper compounds
formed between the light absorption layer adhesion and well, even the formation of alkali metal base layer containing a high
concentration of the solution, The laminated structure and stability, and appearance without problems. Method of the present
invention, the following procedure: the first process,
It is in the Mo electrode layer (2) formed by sputtering the metal layer stack of the In and Cu-Ga alloy layer of precursor
material; precursor attached to the liquid alkali metal with the second process, on through the first and 22 after the
substrate process (1) processing of selenium in selenium-based process; forming the conductive layer of light through the
transparent electrode formation process. As the alkali metal with liquid, you can use sodium borate, sodium sulfide, sodium
aluminum aqueous solution of alkali metal compounds.
