Nanometer sized particles of the chalcopyrite compounds CuInS2 and CuInSe2 were synthesized by thermal decomposition of molecular single-source precursors (PPh3)2CuIn(SEt)4 and (PPh3)2CuIn(SePh)4, respectively, in the non-coordinating solvent dioctyl phthalate at temperatures between 200 and 300 "C. The nanoparticles range in size from 3 30 nm and are aggregated to form roughly spherical cluste...

Transparent energy-harvesting windows are emerging as practical building-integrated photovoltaics (BIPV), capable of generating electricity while simultaneously reducing heating and cooling demands. By incorporating spectrally-selective diffraction gratings as light deflecting structures of high visible transparency into lamination interlayers and using improved spectrally-selective thin-film c...

In this paper, a method to obtain the CuInGaSe2 (CIGS) absorber layer with an appropriate selenium content is put forward, in which a Se-rich target is used to deposit a CIGS thin-film and this film is annealed in a Se-free inert atmosphere. The key issue of this method is the preparation of a Se-rich target with a homogeneous composition and a high-density. The formation mechanism of CuInSe2 a...

Copper indium diselenide thin films have been prepared onto ITO (In2O3:Sn) substrates by a newly developed pulsed electrodeposition method. The proposed scheme consists of a cyclically repeated pulsed potential sequence at the corresponding deposition potentials of elemental Cu, Se and In. When the potential is stepped back to the initial Cu electrodeposition potential after a full cycle to sta...
