ABSTRACT:
Disclosed herein is a light-absorbing layer for a solar cell with enhanced sunlight absorption comprising CuGaSe2, CuIn1-xGaxSe2and CuInSe2thin films laminated one another. Further disclosed is a method of manufacturing the light absorbing layer. The method comprises the steps of: forming an InSe thin film from a single precursor containing In and Se on a substrate by metal organic chemical vapor deposition; forming a Cu2Se thin film using a Cu precursor on the InSe thin film by metal organic chemical vapor deposition; forming a CuGaSe2thin film using a single precursor containing Ga and Se on the Cu2Se thin film by metal organic chemical vapor deposition; and forming a CuGaSe2/CuInSe2multilayer thin-film structure using the single precursor containing In and Se and the Cu precursor on the CuGaSe2thin film by metal organic chemical vapor deposition.
