Figure 7From: Modification of light absorption in thin CuInS2 films by sprayed Au nanoparticlesOptical absorptance spectra of CIS film on glass (ref) and of CIS/Au-NP nanocomposite films on glass. Au nanoparticles were formed by spraying 2 mM HAuCl4 aqueous solution with a volume of 2.5, 10, and 15 ml at 340°C onto the CIS film grown at 310°C.Back to article page
