摘要

Thin films of CdTe semiconductor were electrochemically deposited using two-electrode and three-electrode configurations in potentiostatic mode for comparison. Cadmium sulphate and tellurium dioxide were used as cadmium and tellurium sources, respectively. The layers obtained using both configurations exhibit similar structural, optical, and electrical properties with no specific dependence on any particular electrode configuration used. These results indicate that electrochemical deposition (electrodeposition) of CdTe and semiconductors in general can equally be carried out using two-electrode system as well as the conventional three-electrode system without compromising the essential qualities of the materials produced. The results also highlight the advantages of the two-electrode configuration in process simplification, cost reduction, and removal of a possible impurity source in the growth system, especially as the reference electrode ages.

Summary: In this study, CdTe thin films were successfully grown using a wet-chemical electrochemical technique in an aqueous bath. The effect of bath temperature on the properties of the sample and the optoelectronic performance of the solar cell devices was investigated. The annealed sample exhibited a polycrystalline cubic crystal structure of CdTe with the desired grain size and stoichiometry. The solar cell device showed a relatively high fill factor and efficiency.

Enhanced solar-driven water splitting by ZnO/CdTe heterostructure thin films-based photocatalysts

Mamoona Riffat, Hassan Ali, H. A. Qayyum, M. Bilal, Tanvir Hussain

Summary: Solar-driven hydrogen production using a photocatalyst is the most effective method, and hydrogen is the most suitable renewable energy source. The efficiency of hydrogen production is low, but it can be enhanced by using a suitable photocatalyst. This study deposited ZnO thin films on CdTe thin films to form ZnO/CdTe heterostructure thin films as photoelectrodes for water splitting. The results showed that ZnO/CdTe heterostructure thin films have better photocurrent response and charge transfer compared to pure ZnO and CdTe thin films.

A. U. Yimamu, M. A. Afrassa, B. F. Dejene, O. K. Echendu, J. J. Terblans, H. C. Swart, S. J. Motloung

Summary: Cadmium Telluride (CdTe) thin films were synthesized using a less commonly used salt, cadmium acetate, as a cadmium precursor. The film's structure, optical properties, conductivity, surface morphology, elemental composition, and surface roughness were investigated using XRD, UV-VIS, PEC, SEM, EDS, and SPM. The results showed that the film prepared at a deposition voltage of 1250 mV had better potential application.

Summary: This study critically examines the effects of cadmium chloride treatment and bromine/methanol wet etching on the structural and optical properties of polycrystalline CdTe thin-films. Experimental results were used to determine the spectral dependence of the optical absorption coefficient and to analyze the impact on the grazing incidence x-ray diffraction pattern. The study also extended to analyzing the external quantum efficiency of CdTe-based solar cells treated with cadmium chloride, providing insights into carrier trapping and recombination processes in different types of CdTe absorbers.

Influence of growth time on the properties of CdTe thin films grown by electrodeposition using acetate precursor for solar energy application

A. U. Yimamu, M. A. Afrassa, B. F. Dejene, O. K. Echendu, K. G. Tshabalala, J. J. Terblans, H. C. Swart, S. J. Motloung

Summary: Cadmium telluride (CdTe) thin films were electrodeposited from an aqueous acidic solution, using cadmium acetate dihydrate and tellurium dioxide as precursors. The deposition time was varied to investigate the properties of the CdTe films. XRD analysis revealed polycrystalline cubic zinc blend, orthorhombic, and hexagonal structures in the films, with the dominant cubic phase. UV-vis spectrophotometry showed that the band gap of the as-deposited films ranged from 1.41 to 1.45 eV, but decreased to 1.39-1.42 eV after heat treatment. PEC measurements confirmed n-type conductivity in both forms. SEM analysis showed changes in surface morphology with deposition time, and an increase in grain size after heat treatment. EDS analysis indicated variations in the composition of the films with deposition time, with a decrease in tellurium and an increase in cadmium after annealing. SPM measurements revealed that the average surface roughness varied with deposition time, with the highest value observed for the 120 min deposition. The prepared CdTe films show potential as absorber layers in thin film solar cells.

Application of locational CdCl2 treatment to CdS thin films grown on an ultra-thin MgZnO for CdTe solar cells

Ali Ciris

Summary: This study investigated the impact of locational CdCl2 treatment on the MgZnO/CdS stacks. The application of CdCl2 to either the inter-face or the top-surface improved the grain structure of the stacks, while CdCl2 applied to both surfaces led to a porous structure. CdS and MgZnO absorption edges were observed in all stacks, along with emission bands relating to defect transitions in the MgZnO and CdS layers. The refractive index values decreased with CdCl2 treatment. The results suggest that local CdCl2 treatment has a clear effect on the structural and optical properties of MgZnO/CdS stacks.
