  1. 1. Solution-Chemically Derived Spectrally Selective Solar Absorbers : With System Perspectives on Solar Heating

    Author : Tobias Boström; Ewa Wäckelgård; Gunnar Westin; Björn Karlsson; Peter Lund; Uppsala universitet; []
    Keywords : Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

    Abstract : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. READ MORE

  2. 2. Spectrally Selective Solar Absorbing Coatings Prepared by dc Magnetron Sputtering

    Author : Shuxi Zhao; Ewa Wäckelgård; Carl-Gustaf Ribbing; Volker Wittwer; Uppsala universitet; []
    Keywords : Materials science; spectrally selective surface; solar energy; magnetron sputtering; thin film; Materialvetenskap;

    Abstract : Spectrally selective solar absorber using composite Ni-NiO as coating materials was studied. Samples were prepared by dc magnetron sputtering unit named Rulle, which is a miniature copy of an industrial roll-coater unit. READ MORE

    Abstract : In this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy.
