Thin-film ZnO/CdS/CuIn1−xGaxSe2 Solar Cells: Anomalous Physical Properties of the CuIn1−xGaxSe2 Absorber

On microscopic compositional and electrostatic properties of grain boundaries in polycrystalline CuIn1−xGaxSe2

CuIn1-xGaxS2 thin film solar cells with ZnxCd1-xS as heterojunction partner

Copper indium gallium sulfide, CuIn1-xGaxS2 (CIGS2) solar cells prepared with chemical bath deposited heterojunction partner zinc-cadmium sulfide (ZnxCd1-xS) layer has exhibited better blue photon response and in turn, higher currents. This can be attributed to its higher bandgap than that of CdS. The open circuit voltages for CIGS2/ZnxCd1-xS were also higher than those of the CIGS2/CdS devices...

Investigation of Physical Properties of e-Beam Evaporated CdTe Thin Films for Photovoltaic Application

CdTe thin films with 2.8 µm thickness were deposited by electron beam evaporation method. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and atomic force microscopy (AFM) were used to characterize the films. The results of AFM analysis revealed that the CdTe films have uniform surface. CdTe thin films were heat-treated by SnCl2 solution. Structural analysis using XRD s...

Characterisation of Thin Films CuIn1-xAlxSe2 Prepared by Selenisation of Magnetron Sputtered Metallic Precursors

Thin films of CuIn1-xAlxSe2 have been produced by the selenisation of magnetron sputtered Cu/In/Al precursor layers using elemental selenium and the chemical and physical properties of the layers have been determined for different conditions of synthesis. For optimum conditions of synthesis it was found possible to produce single phase films with the chalcopyrite structure. These films were pin...

One-pot electrodeposition, characterization and photoactivity of stoichiometric copper indium gallium diselenide (CIGS) thin films for solar cellswzy

Herein we report the one-pot electrodeposition of copper indium gallium diselenide, CuIn1 xGaxSe2 (CIGS), thin films as the p-type semiconductor in an ionic liquid medium consisting of choline chloride/urea eutectic mixture known as Reline. The thin films were characterized by scanning electron microscopy with energy dispersive X-ray analysis, transmission electron microscopy, X-ray photoelectr...
