Solar cells based on black silicon (b-Si) are proven to be promising in photovoltaics (PVs) by exceeding 22%efficiency. To reach high efficiencies with b-Si surfaces, the most crucial step is the effective surface passivation. Up to now, the highest effective minority carrier lifetimes&...

This article reports the fabrication and characterization of thin films of pure and cobalt doped ZnO (Co at 4% and 7%), a transparent diluted magnetic semiconductor (DMS) grown on ‘Si’ and glass substrates by RF magnetron sputtering technique. The crystalline structure and phase of...

This paper deals with the topic of composite insulation materials for rotating machines and it is primarily pointed to the synthesis of new three-component insulation system. In connection with this research, the basic components of the insulation system are selected and described by&#x...

We report the synthesis and characterization of silicon nanostructures obtained by thermal annealing of silicon-rich oxide/silicon dioxide (SRO/SiO2) multilayers deposited by magnetron sputtering in an argon and oxygen atmosphere. The main motivation to study silicon comes from its success a...

Highly polymorphic cobalt sulfide represents attractive material because of its unique electronic, optical, magnetic, mechanical and catalytic properties. Pulsed laser irradiation of a solid CoS2 target results in ablation and deposition of thin films on Ta and Cu substrate, which were analy...

Aluminum-doped zinc oxide (AZO) is a promising candidate to replace ITO film as transparent electrode. Due to its lower price it is applied in the production of silicon solar cells, however, it is difficult to obtain suitable electrical properties at low deposition temperatures. Mo...

Barium di-silicide (BaSi2) has been regarded as a promising absorber material for high-efficiency thin-film solar cells. However, it has confronted issues related to material synthesis and quality control. Here, we fabricate BaSi2 thin films via an industrially applicable sputtering process and&#...

Reactive high-power impulse magnetron sputtering was used for high-rate (deposition rate of 60 nm/min) deposition of conductive (resistivity of 0.003 Ω·cm) and optically transparent (extinction coefficient at the wavelength of 550 nm of 0.01) ZnO:Al thin films at ambient temperature (<&#x...

This work presents a detailed study of aluminium-doped zinc oxide thin films sputtered at 100 °C, with a focus on the correlation between structural and electrical properties. The structural properties are identified by SEM microscopy and X-ray diffraction, while the electrical properties ...

Optical and magnetic features of the A2V2O2 (A = Fe and Co) compounds are explored. Density functional theory (DFT) within a framework of FPLAPW (full-potential linearized augmented plane wave) method, as well as generalized gradient approximation plus the Hubbard parameter (GGA+U) and ...

In the present work co-sputtering from ceramic and metallic targets is used to reduce the oxygen content in aluminium doped zinc oxide. Films with thickness between 200 and 220 nm are sputtered at 100 and 250 °C and investigated by X-ray diffraction, energy dispersive spectros...

Invasive pulmonary aspergillosis results in 450,000 deaths per year and complicates cancer chemotherapy, transplantations and the treatment of other immunosuppressed patients. Using a rat model of experimental aspergillosis, the fungal siderophores ferricrocin and triacetylfusarinine C were identified as m...
