Polycrystalline CuInSe2 (CISe) nanorods are promising for the fabrication of highly efficient active layers in solar cells. In this work we report on a nanocasting approach, which uses track-etched polycarbonate films as hard templates for obtaining three-dimensionally (3D) arranged CISe nanorod arrays. Copper and indium ketoacidoximato complexes and selenourea were employed as molecular precur...

High-quality CuInSe2 nanoparticles have been prepared by the solution phase synthesis procedure utilizing copper acetate or cuprous chloride as the Cu-precursor, indium chloride as the In-precursor and selenium powder as Se precursor, respectively. The synthesis process was optimized to grow 20 to 150 nm sized nanostructures of CuInSe2, and the Cu to In ratio as well as the kind of Cu-precursor...

The reaction pathway and kinetics of a-CuInSe2 formation from a glass/In2Se3/CuSe polycrystalline bilayer precursor film were investigated using time-resolved, in situ high-temperature X-ray diffraction. Bilayer glass/In2Se3/CuSe precursor films were deposited on thin glass substrates in a migration enhanced molecular beam epitaxial deposition system. These films were then temperature ramp anne...

In situ high-temperature X-ray diffraction was used to investigate the reaction mechanism and kinetics of a-CuInSe2 formation from Cu–In precursors during selenization. The precursor films were deposited in a migration-enhanced molecular beam epitaxial reactor on Mo-coated thin glass substrates. During the selenization, the formation of CuSe was observed, followed by its transformation to CuSe2...

Excitonic quality CuInSe2 crystals were studied using low-temperature (10 K) photoluminescence (PL) excited by continuous wave and nanosecond pulsed lasers at power densities from 0.01 to 76 kW/cm2. Increasing the excitation density level 26 kW/cm2 resulted in appearance of a stimulated emission SE-band PL spectra 1.035 eV. Further increase 39 generated on top SE band, structure equidistant sha...
