    • Characterisation of photochromic oxygen-containing yttrium hydride by electron microscopy 

      Ånes, Håkon Wiik (Master thesis, 2017)
      Smart windows based on chromogenic materials have in recent years emerged as promising candidates for the next generation of energy-efficient windows. One group of chromogenic materials are photochromic, which are characterised ...

    • Clustering during Natural Aging and its Effect on Precipitation Hardening in Al-Mg-Si Alloys 

      Martinsen, Fredrik Aleksander (Master thesis, 2011)
      The effect of clustering during natural aging of three different Al-Mg-Sialloys with equal Mg/Si-ratios, but different Mg+Si contents have beenstudied through hardness measurements and transmission electron mi-croscopy ...

    • Light trapping in horizontally aligned silicon microwire solar cells 

      Martinsen, Fredrik Aleksander; Smeltzer, Benjamin; Ballato, John; Jones, Maxwell; Hawkins, Thomas A.; Gibson, Ursula (Journal article; Peer reviewed, 2015)
      In this study, we demonstrate a solar cell design based on horizontally aligned microwires fabricated from 99.98% pure silicon via the molten core fiber drawing method. A similar structure consisting of 50 μm diameter close ...

    • Silicon microwires as solar cells 

      Martinsen, Fredrik Aleksander (Doctoral thesis at NTNU;2015:235, Doctoral thesis, 2015)
      In this work it has been shown that microwire radial junction solar cells can be realized from silicon core glass fibers made via the molten core fiber drawing method starting with low quality silicon. Through a ...

    • The impact of advanced glazing on colour perception 

      Arbab, Shabnam; Matusiak, Barbara Szybinska; Martinsen, Fredrik Aleksander; Hauback, Bjørn (Journal article; Peer reviewed, 2017)
      The aim of this study was to expand the understanding of modern glazing materials’ effects on the perception of colours. To this end, the appearance of eight standard CIE test colour samples were ...
