FEKT-DET1AAcad. year: 2012/2013

Part I. offers the description of the nature of anisotropic materials in general, with more detailed application at piezoelectric materials. It describes linear theory of piezoelectricity, components and systems, production processes of various piezoelectric systems included.
Part II. The Physics of the Solar Cell, Photovoltaic sources, principle of function and characteristics. Basic types of photovoltaics systems and aplications. Manufacturing of Monocrystalline, Polycrystalline, amorphous Siliconbased Solar Cells, CdTe, CuSe, InGa Solar Cells. Dye-sensitized Solar Cells. Solar modules, construction and technology.
Part III. will deal with special materials proposed for the use in biomedical praxis. The sensors and special electrodes will be described in one of the main chapters. Another chapter will contain knowledge on new electrochemical power sources, the corrosion and lifetime of materials in biological environment and to the compatibility if implanted devices in tissues.
Part IV. Solder joint, solder joint formation. Requirements for solder joint. Reliability of solder joint - material and process factors.
