“…CdS thin films exhibit a high transparency in the visible spectrum and a band gap value of 2.45 eV. These make them a promising entrant for a wide range of applications, such as solar cells, optoelectronic devices, and sensors. − Improving and controlling the properties of CdS films is compulsory if we want to make those devices more efficient. − The results achieved during this investigation contribute to a deeper understanding of the effects of chromium doping on CdS thin films, stimulating the development of new devices and applications based on these materials.…”

In this research work, a material system formed of cadmium sulfide combined with chromium atoms was developed to evaluate the influence of chromium concentration on the optical, electrical, structural, and morphological properties of a precursor layer of CdS. It is possible to observe that the transmission spectra increased for all chromium concentrations analyzed. From X-ray diffractograms, we conclude more accurately that CdS presents a mixture of phases, including orthorhombic, hexagonal, and cubic. Furthermore, the impact of adding chromium results in variations in the intensity of two major peaks in the diffractograms and an anomalous shift in the CdS pattern. The calculated resistivities show an invariable behavior of 4.5 × 10 6 Ω cm. In addition, the bandgap values remain practically constant, with values of approximately 2.43−2.44 eV. The addition of chromium at different concentrations leads to surface morphology changes, as observed in SEM images.

“…In past studies, CdS films doped with rare-earth elements such as terbium, ytterbium, praseodymium, neodymium, and europium have also been documented. − Semiconductor nanoparticles enriched with lanthanide ions offer notable benefits, especially in the realm of fluorescence labeling. These ions facilitate multicolor imaging using a single-wavelength excitation by harnessing diverse ions.…”

This work is aimed at investigating the viability of utilizing cadmium sulfide (CdS) as a buffer layer in CdTe solar cells by analyzing and assessing its optical, photoluminescence, morphological, and electrical properties. These films were fabricated using a thermal coating technique. Optical microscopy was used to observe the changes in morphology resulting from the doping of rare-earth metals such as samarium (Sm) and lanthanum (La) to CdS, while the granular-like structure of the sample was confirmed by scanning electron microscopy. The objective of incorporating Sm and La ions into CdS was to enhance photoconductivity and optimize the optical bandgap, aiming to create a viable charge transport material for photovoltaic devices with enhanced efficiency. Through that process, a noticeable decrease in transmission, from approximately 80 to 68% in the visible region, was observed. Additionally, the bandgap value was reduced from 2.43 to 2.27 eV. Furthermore, during the analysis of the photoluminescence spectra, it was observed that emission peaks occurred in the visible region. These emissions were attributed to electronic transitions that took place via band-to-band and band-to-impurity interactions. The electrical measurements showed an enhancement in conductivity due to the decrease in the bandgap. This notable consequence of the doped materials suggests their utilization in photovoltaic systems.
