As a reference active layer, poly(3-hexylthiophene-2 5-diyl) and 6,6-phenyl-C71-butyric acid methyl ester arrangement was used. Absorption and luminescence spectra were determined for CdSe/ZnS quantum dots. The dispersion relations for optical constants were determined for pure quantum dots and matrixes using ellipsometric spectroscopy. The morphologies of the thin film layers were performed using Atomic Force Microscope (AFM). Chemical boundings for ternary layers were obtained by Raman spectroscopy. Based on UPS studies, the energy diagram of the potential devices was determined. Impedance spectroscopy studies were also performed to obtain layers resistance. The performance results of organic cells with donor active layers doped with quantum dots were obtained using General-Purpose Photovoltaic Device Model (GPVDM) software.

This work reviews the latest developments in the quinoline derivatives (metal complexes) for applications in the photovoltaic cells. Their properties for photovoltaic applications are detailed: absorption spectra, energy levels, and other achievements presented by the authors. We have also outlined various methods for testing the compounds for application. Finally, we present the implementation of quinoline derivatives in photovoltaic cells. Their architecture and design are described, and also, the performance for polymer solar cells and dye-synthesized solar cells was highlighted. We have described their performance and characteristics. We have also pointed out other, non-photovoltaic applications for quinoline derivatives. It has been demonstrated and described that quinoline derivatives are good materials for the emission layer of organ...

We used ion implantation to modify the properties of Cu2O oxide. Thin films of Cu2O were deposited with magnetron sputtering and implanted with low-energy Cr ions of different dosages. The X-ray diffraction method was used to determine the structure and composition of deposited and implanted films. The optical properties of the material before and after implantation were studied using spectrophotometry and spectroscopic ellipsometry. The investigation of surface topography was performed with atomic force microscopy. The implantation had little influence on the atomic lattice constant of the oxide structure, and no clear dependence of microstrain or crystalline size on the dose of implantation was found. The appearance of phase change was observed, which could have been caused by the implantation. Ellipsometry measurements showed an increase in the total thickness of the sample with...

To improve its properties, the oxide was doped with a metallic element. No studies were previously performed on Cr-doping using the ion implantation technique. The research goal of these studies is to investigate how Cr ion implantation impacts the properties of the oxide thin films. CuO thin films were deposited using magnetron sputtering, and then chromium ions with different energies and doses were implanted. Structural, optical, and vibrational properties of the samples were studied using X-ray diffraction, X-ray reflectivity, infra-red spectroscopy, Raman spectroscopy, and spectrophotometry. The surface morphology and topography were studied with ellipsometry, atomic force microscopy, and scanning electron microscopy. A simulation of the range of ions in the materials was performed. Ion implantation had an impact on the properties of thin films that could be used to tailor th...

Such materials must be characterized by improved heat resistance, especially to radiation and flame. In this paper, fireproof fabric (NATAN and PROTON—trademark names) was covered with Ti-Si-N nanocomposite reflective coating using magnetron sputtering. The fabrics were subjected to heat radiation of heat flux density from 0.615 to 2.525 kW/m2. A testing stage equipped with a heat source, thermal imaging camera and thermocouples was used. Two variants of the coatings were studied: Ti-Si and (Ti,Si)N considering different thicknesses of layers. The temperature increment and time to reach the pain threshold (60 °C) which corresponds approximately to a 2nd-degree burn according to Henriques criterion were analyzed. In addition, the microstructural analysis of the samples using a scanning electron microscope (SEM) equipped with energy dispersive spectroscopy (EDS) system was performed. The improvement of heat resistance s...

After deposition, the films were annealed at previously confirmed conditions (400 °C/4 h/synthetic air) and further investigated by utilization of X-ray diffraction (XRD), X-ray reflectivity (XRR), energy-dispersive X-ray spectroscopy (EDS). The gas-sensing behavior was tested in the air/acetone atmosphere in the range of 0.1–1.25 ppm, as well as at various relative humidity (RH) levels (10–85%). The highest responses were obtained for samples based on the CuO-Ga2O3 (4% at. Ga).

W pracy przeanalizowano wpływ pokryć antyrefleksyjnych zarówno na powierzchni szkła modułu fotowoltaicznego jak i stosowanych warstw ARC na powierzchni ogniw słonecznych na bazie krzemu na właściwości optyczne systemu. Wyznaczono rekomendowane wartości współczynników załamania oraz grubości pokryć. Wyliczone wartości pozostają w zgodności z wynikami pomiarów optycznych.
