  2. 1. Generic Properties of Polymer Solutions

    Author : Takashi Uematsu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Abstract : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. READ MORE

  6. 4. Cadmium Free Buffer Layers and the Influence of their Material Properties on the Performance of Cu(In,Ga)Se2 Solar Cells

    Author : Adam Hultqvist; Charlotte Platzer-Björkman; Tobias Törndahl; Marika Edoff; Takashi Minemoto; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cu In; Ga Se2; Solar cells; Thin film; Buffer layer; Window layer; ZnO; Zn O; S ; Zn; Mg O; Zn-Sn-O; Semiconductor physics; Halvledarfysik; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : CdS is conventionally used as a buffer layer in Cu(In,Ga)Se2, CIGS, solar cells. The aim of this thesis is to substitute CdS with cadmium-free, more transparent and environmentally benign alternative buffer layers and to analyze how the material properties of alternative layers affect the solar cell performance.
