Figure 4From: Modification of light absorption in thin CuInS2 films by sprayed Au nanoparticlesXRD patterns of CIS film as a reference and CIS/Au-NP nanocomposite films. Au nanoparticles are prepared by spray of 2.5, 10, and 15 ml of 2 mM HAuCl4 aqueous solution at 340°C onto CIS film previously grown at 310°C.Back to article page
