Development of materials for photovoltaic technology of II. generation
(on thin films)

The subject of the research is deposition and characterization physical properties of transparent conductive oxides (TCO), especially ZnO:Al as well as amorphous hydrogenated silicon. Deposition of thin films TCO are deposited by PVD device BOC Edwards TF600 RF magnetron sputtering. Experimental methods for following properties includes especially X-ray diffraction, UV-Vis spectrometry and scanning electron microscopy.

Reasearch of structure and properties of zirconium alloys

Zirconium alloys are used as protective films of nuclear fuel in boiling water reactors and pressurized water reactors. The research includes investigation of real structure and high-temperature phase transformations measured „In Situ“. Further is indentation hardness and oxygen content determined by EDX microprobe researched. The indentation hardness measurement is performed with using of NanoIndenter XP with CSM (continuous stiffness measurement).
