The ever-increasing demand for energy and depletion of conventional energy resources leads to research and development in the area of renewable energy sources. Copper zinc tin sulfide (CZTS) or kesterite based thin film solar cell is an emerging area and is composed of earth abundant, nontoxic and cheaper materials. Absorber layer for the many of the kesterite based solar cells are typically deposited...
DLC and metal/DLC nanocomposites coatings deposited by means of pulsed laser deposition /PLD/ technique, using high power UV nitrogen laser are described. The DLC and M/DLC nanocomposite coatings are deposited on substrates stents made from 316L SS material and NITINOL (NiTi) alloy. The tests and analysis of the morphology-, structure-, physical-, mechanical- electrochemical- and chemical parameters...
Hydrogenated silicon (Si:H) thin films were deposited at a selected argon diluting ratio under varied RF power density and the influence of it on nanocrystallization was studied by XRD, FTIR and Raman spectroscopy.
Summary form only given. Successful deposition of nano-phase crystalline TiO2 thin films on polymeric substrates, polymethylmethacrylate (PMMA) and knitted polyethylene (PE) at room temperature was achieved using the dense plasma focus (DPF) device. Deposition was achieved using argon- oxygen gas mixture in the ratio of 9:1 after evacuating the chamber to a base pressure of 10-5 mbar. The working...
This work aims to investigate the influence of the energy and flux of the ions striking the substrate on the characteristics of the ZrCN coatings deposited by cathodic arc method. The coatings were investigated for elemental and phase composition, chemical binding state, texture, residual stress, hardness, adhesion and tribological behavior using GDOS, Raman spectroscopy and XRD techniques, surface...
This paper describes the possibilities of obtaining nanostructured TiO2 using Spray Pyrolysis Deposition and its application in a solid state solar cell (FTO/ TiO2 In2S3/ CuSbS2/ graphite). Nanostructured TiO2 films are deposited from ethanolic solution of titanium (IV) isopropoxid, (TTIP, 99.99%, Sigma-AIdrich), and acetilacetonate, (AcAc, 99+%, Aldrich); two parameters are proposed for investigation:...
Raman microprobe spectroscopy and scanning electron microscopy were used to study the initial nucleation and growth of YBCO in thick precursors by the BaF2 ex situ process. For quenched films of 2 mum thickness, the data indicate a low density of c-axis nuclei near the substrate, apparently due to a reduced oxygen concentration deep inside the precursor layer. Significant non c-axis growth was also...
