박막 태양전지용 금속 캘코젠 단일 전구체 합성 및 응용 = Synthesis and application of metal chalcogenide single precursors for thin film solar cell

다국어 초록 (Multilingual Abstract)

In this study, novel metal chalcogenide single precursors have been synthesized and characterized for inorganic thin film solar cell. The novel precursors synthesized are [Cu(dmampS)]4 (I), In(dmampS)2Cl (II), In(dmampS)3 (III), In(dmampS)2SeCN (IV), In(dmampS)2SCN (V), Ga(dmampS)2Cl (VI), Ga(dmampS)3 (VII), Ga(dmampS)2SeCN (VIII), Ga(dmampS)2SCN (IX), Zn(dmampS)2 (X), and Sn(dmampS)2 (XI), where dmampS is 1-(dimethylamino)-2-methylpropane-2-thiolate. The compounds were characterized by FT-IR, 1H NMR, spectroscopy, elemental analysis, and mass spectrometry. X-ray single crystallography study shows that I, X, and XI are tetrameric, tetrahedral, and seasaw structure, respectively while all of II, IV, VI, VIII, and IX reveal a distorted trigonal bipyramidal geometry at a metal center. Thermal decomposition of I, III, X, XI under nitrogen atomosphere resulted in the formation of Cu2S, In2S3, ZnS, SnS, respectively. CZTS nanoparticles was also prepared by the thermal decomposition of a mixture of I, X and XI precursors.
