PREPARATION METHOD OF CIS-BASED OR CZTS-BASED COLLOIDAL SOLUTION BY WET TYPE BALL MILLING PROCESS AND METHOD FOR PREPARING CIS-BASED OR CZTS-BASED COMPOUND THIN FILM AS AN OPTICAL ABSORBER LAYER OF SOLAR CELL USING THE SAME

摘要

Proper composition of the present invention is necessary for the synthesis of the CIS-based compound that consists of IB-IIIA-VIA group elements by a ball mill to perform the solution phase method for the elemental powder with a specific production method of the CIS-based solvent, characterized in that the colloidal solution is produced, production of the CIS-based compound, characterized in that the nano powder CIS-based colloidal solution is prepared by heating a method and to a method for producing the CIS-based colloidal solution which is characterized in that which is prepared by coating on a substrate solar cell light absorption CIS-based compound film. According to the present invention when manufacturing the solar cell-based CIS light absorption layer of a CIS-based compound thin films compound thin film is used as the residue element powder is required to cause a decrease in efficiency does not remain uniform tetragonal crystal structure having a political can be prepared CIS-based solar cell light absorption layer compound thin film with a non-vacuum methods. ;
