Synthesis, characterization and application of nanocrystalline CdZn(SeTe)2 thin films for energy application

In the present investigation CdZn(SeTe)2 thin films were successfully synthesized via a simple and cost effective arrested precipitation technique (APT). It was found that the tellurium play an important role in determining the optostructural, morphological, compositional and photoelectrochemical (PEC) performance of CdZn(SeTe)2 thin films. The optical absorption analysis indicates the direct allowed type transitions and band gap of CdZn(SeTe)2 thin films were change with respect to Te content. X-ray diffraction (XRD) studies revealed that the films were nanocrystalline in nature with rhombohedra and hexagonal crystal structure. The surface morphology of CdZn(SeTe)2 thin films were scanned by employing scanning electron microscopy (SEM) and morphology get improved with respect to Te content. Compositional analysis of all samples was carried out using energy dispersive X-ray spectroscopy (EDS) which confirms the presence of elements in CdZn(SeTe)2 thin films. Finally prepared electrodes were tested for their PEC performance in polysulphide electrolyte. It was observed that CdZn(SeTe)2 nanorods exhibits the best photovoltaic performance.In the present investigation CdZn(SeTe)2 thin films were successfully synthesized via a simple and cost effective arrested precipitation technique (APT).
