Its implementation can effectively reduce charge transport losses from the CdTe absorber layer to the back electrode, typically composed of Cu/Au. In this study, CuI thin films with thicknesses ranging from 2 to 100 nm were deposited via physical vapor deposition (PVD). The optoelectronic, morphological, and structural properties of these films were systematically analyzed both with and without post-deposition thermal treatment. Based on these analyses, each CuI film, 6, 20, 40, 60, and 100 nm thick (as grown), was integrated as a buffer layer in four CdS/CdTe solar cells. The obtained data had a low standard deviation, showing low dispersion and good reproducibility. Among these, the 20 nm CuI buffer layer exhibited the best performance, surpassing the reference solar cell without a buffer layer. The optimized devices exhibited a 44% increase in short-circuit current density and a 29% improvement in power conversion efficiency on average, despite a 3% decrease in open-circuit voltage compared to the control cell. Since copper diffusion is the primary issue that reduces the lifetime of CdS/CdTe solar cells, it is expected that the lifetime will increase as the metallic copper back contact is replaced with CuI.

The composition, microstructure, spectroscopic, dielectric and thermoelectric properties are characterized to identify the influence of rare earth ions on the strontium titanate.

The interaction of rare earth ions with strontium titanate reduces the band gap from 3.24 to 2.8 eV. The dielectric response as a function of frequency and temperature reveals detailed electrical properties of the material.

The activation energy decreases with increasing frequency. Frequency exponent (s) values below unity indicate translational motion with sudden hopping transitions. The real (M′) and imaginary (M″) parts of the electrical modulus confirm thermal activation and suggest a transition from long-range to short-range mobility with rising frequency.

However, the formation of iron sludge limits the practical application of homogeneous iron-based catalysts for activating H2O2 and PDS. Therefore, heterogeneous catalysis offers a promising alternative. This study compares the degradation of norfloxacin (NOR) using FeOOH-activated PDS and H2O2 in a photocatalytic system. Hydroxylamine (HA) was employed to assist the activation process to further optimize the degradation process and improve the degradation efficiency. Without the presence of HA, the findings revealed that the degradation rates of NOR were merely 31.2% in the PDS system and 24.8% in the H2O2 system. The introduction of HA markedly improved NOR degradation efficiency, achieving removal rates of 89.7% in the PDS system and 56.3% in the H2O2 system. Key operational parameters including pH, HA concentration, oxidant dosage, and the presence of HA were systematically evaluated for their influence on degradation performance. Scavenging experiments revealed that ⋅OH, SO4−⋅, and ⋅O2− served as the dominant reactive species in the PDS system, whereas h+ and ⋅OH were the primary drivers in the H2O2 system. Based on these findings, a plausible reaction mechanism was proposed. Additionally, the stability of the FeOOH catalyst in the presence of HA and its effectiveness in degrading NOR across various water matrices were investigated. This study offers an innovative strategy for visible-light-assisted activation of H2O2 and PDS, demonstrating considerable potential for antibiotic degradation in water treatment applications.</div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 26","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
