  4. 2. 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

  5. 3. Solar cavity receiver design for a dish-Stirling system

    Author : Jorge Garrido Gálvez; Björn Laumert; Uwe Gampe; KTH; []
    Keywords : Concentrating Solar Power; Solar receiver; Solar simulator; Uncertainty analysis; Monte Carlo ray tracing; Experimental validation; Coatings; System modeling; Structural analysis; Creep damage; Thermal stress; Cavity receiver design; Energy Technology; Energiteknik;

    Abstract : The growing concern for the climate change has led to an increasing research effort in renewable energy technologies in order to achieve a more sustainable electricity production. Concentrating Solar Power (CSP) is identified as a promising technology to deal with part of the future electricity production. READ MORE

  6. 4. Solar heat pump systems for heating applications : Analysis of system performance and possible solutions for improving system performance

    Author : Stefano Poppi; Per Lundqvist; Chris Bales; Kai Siren; KTH; []
