Chaos enhanced light trapping in optically thin solar cells
Seim, Eivind (PhD thesis;2020:3, Doctoral thesis, 2020)Photovoltaics is one of the most important sources of renewable energy. Solar cells with thin absorbing layers can be more cost-effective and leave a smaller environmental footprint than the current commercial technology. ... -
Hyperspectral imaging as a tool for characterization of multicrystalline silicon wafers
Flø, Andreas Svarstad (PhD Thesis;2014:21, Doctoral thesis, 2014)This thesis describes the development of a method for characterization of multicrystalline silicon wafers based on hyperspectral imaging. The aim has been to show the distribution of radiative defects in silicon wafers. ... -
Hyperspectral photoluminescence imaging of silicon wafers and solar cells
Mehl, Torbjørn (PhD Thesis;2018:59, Doctoral thesis, 2018)Hyperspectral photoluminescence imaging is a non-destructive characterization method used to study radiative defects in crystalline silicon wafers and solar cells. It provides both spatial distribution and spectral response ... -
Scattering and absorption in nano- and microstructured media
Brandsrud, Maren Anna (PhD thesis;2020:51, Doctoral thesis, 2020)When electromagnetic radiation interacts with objects of the same wavelength as the radiation, the objects can act as resonators and strong scattering effects appear. The goal of this PhD project has been to understand ... -
The potential of molten salts as heat transfer media in fast pyrolysis of wood
Nygård, Ruth Heidi Samuelsen (PhD Thesis;2015:1, Doctoral thesis, 2020-11-04)Growing energy consumption and greater environmental concerns have contributed to a need for more research on alternatives to fossil-derived products. Biomass such as wood is a potential source of renewable fuels and ... -
Toward monitoring of photovoltaic power plants with photoluminescence imaging
Vukovic, Marija (PhD Thesis;2023:53, Doctoral thesis, 2023)It is predicted that the photovoltaic energy conversion will be the largest installed power capacity by 2027. The least costly option for new electricity generation in many of the world’s countries will be the utility-scale ...
