  2. 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

  4. 2. Preparation and Characterization of Sputter Deposited Spectrally Selective Solar Absorbers

    Author : Kristina Gelin; Ewa Wäckelgård; Arne Roos; Björn Karlsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; spectrally selective solar absorber; thermal emittance; solar absorptance; sputter deposition; infrared reflectance; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : The optical efficiency of a commercially available sputter deposited spectrally selective solar absorber was improved. The main purposes were to decrease the thermal emittance, increase the solar absorbtance of the absorber and to protect the substrate from degradation due to environmental influence. READ MORE

  5. 3. 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
