  3. 3. Optical Design and Characterization of Solar Concentrators for Photovoltaics

    Author : Johan Nilsson; Energi och ByggnadsDesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Stationary solar energy concentrators are a promising option for decreasing the price of photovoltaic electricity. This thesis studies stationary concentrators in PV/Thermal applications. The studied systems are parabolic troughs intended for building integration. The first chapters briefly explain the optics of solar energy concentrators. READ MORE

  4. 4. Optical Characterization of Solar Collectors form Outdoor Measurements

    Author : Anna Helgesson; Energi och ByggnadsDesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to high installation costs and relatively low output, the active use of solar energy is limited. The output from a collector can be improved e.g. by using a selective absorber, AR-treated cover glass or transparent insulation. READ MORE
