Pubtime:2010/4/18 12:34:41        Total Views:570

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.
