2. 1. Nanoparticle plasmon influence on the charge carrier generation in solar cells

   Author : Carl Hägglund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; solar cells; finite element method; nanoparticle plasmons; photovoltaics; nanofabrication; Si; dye sensitized solar cells; localized surface plasmon resonances;

   Abstract : Global warming is a potential threat to life on earth and to human society. It is by much evidence linked to the extensive use of fossil fuels in our present energy system. Replacing the fossil fuels by alternative sources of energy poses a tremendous challenge for mankind, but is not at all undoable. READ MORE

4. 2. Solar Thermal Collectors at High Latitudes : Design and performance of non-tracking concentrators

   Author : Monika Adsten; Manuel Collares-Pereira; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Solar thermal collectors; concentrators; CPC; high latitudes; Materialvetenskap; Solfångare; koncentratorer; höga latituder; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : Solar thermal collectors at high latitudes have been studied, with emphasis on concentrating collectors. A novel design of concentrating collector, the Maximum Reflector Collector (MaReCo), especially designed for high latitudes, has been investigated optically and thermally. READ MORE

5. 3. Radar Probing of the Sun

   Author : Mykola Khotyaintsev; Bo Thide'; Valentyn Mel'nyk; Christian Hanuise; Uppsala universitet; []
   Keywords : Space and plasma physics; solar radar; active experiments; space physics; solar corona; plasma; Rymd- och plasmafysik;

   Abstract : This thesis is dedicated to the theory of solar radar experiments. The Sun exhibits a variety of interesting and complicated physical phenomena, examined mainly through analysis of its radiation. Active solar probing by radar provides an alternative possibility to study the Sun. READ MORE

6. 4. Thermal stresses in load-bearing glass-timber components

   Author : Karin Lundstedt; Erik Serrano; Ola Dahlblom; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermal stresses; thermal failure; glass and wood construction; incident solar radiation; shading; cracks; temperature difference; finite element method.; Technology byts ev till Engineering ; Teknik;

   Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation:  that is, sunlight.  The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas.

7. 5. Climate Related Thermal Actions for Reliable Design of Concrete Structures

   Author : Oskar Larsson; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stress; solar radiation; FE-analysis; climate data; box-girder bridge; KstrConcrete; KstrReliability;

   Abstract : When the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. READ MORE
