dc.description.abstract | Kesterite materials were investigated for their suitability as absorber layers for thin-film photovoltaic cells. Thin-
films of copper cadmium zinc tin sulfide (Cu2CdxZn1-xSnS4) were prepared by spray pyrolysis on soda-lime glass.
The obtained thin-films were subjected to post annealing treatment at 525 ◦C in a sulfur atmosphere to study the
effects on morphology, stoichiometry, phase formation and optical properties by scanning electron microscopy
(SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and ultraviolet visible spectroscopy
(UV–Vis). The XRD patterns revealed the presence of prominent kesterite peaks in the unannealed and annealed
thin-films, with enhanced crystallinity in the annealed thin-films. The crystal sizes of the unannealed and
annealed thin-films were estimated from the XRD data and ranged from 5 nm to 27 nm for unannealed thin-films
and 13 nm–25 nm for annealed thin-films. The unannealed thin-films exhibited a non-uniformly shaped
morphology, which was a mixture of cube-shaped and rod-shaped nanoparticles, while the annealed thin-films
exhibited a uniformly shaped morphology of flake-shaped nanoparticles, indicating enhanced crystallinity. | en_US |
