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. ... -
An exact ray model for oblique incident light on planar films
Brandsrud, Maren Anna; Blümel, Reinhold; You, Chang Chuan; Marstein, Erik Stensrud; Seim, Eivind; Lukacs, Rozalia; Olsen, Espen; Kohler, Achim (Peer reviewed; Journal article, 2021)During recent years, ray tracing has frequently been used to study the absorption characteristics of structured solar cells. However, wave properties such as absorption enhancement due to resonances in optically thin solar ... -

Exact ray theory for the calculation of the optical generation rate in optically thin solar cells
Brandsrud, Maren Anna; Seim, Eivind; Lukacs, Rozalia; Kohler, Achim; Marstein, Erik Stensrud; Olsen, Espen; Blümel, Reinhold (Journal article; Peer reviewed, 2018)There is a profound duality between rays and waves. In fact, 70 years ago, in the context of quantum mechanics, Feynman showed that rays, properly equipped with phases and correctly summed, provide exact solutions of the ... -

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 ... -
