Beyond the 2D limit: étendue-squeezing line-focus solar concentrators
Johnsen, Håkon Jarand Dugstad; Aksnes, Astrid; Torgersen, Jan (Peer reviewed; Journal article, 2020)Line-focus solar concentrators are commonly designed by extruding a two-dimensional concentrator in the third dimension. For concentration in air, these concentrators are, by the nature of their design, limited by the ... -
Cochlea-inspired tonotopic resonators
Dal Poggetto, Vinícius F.; Bosia, Federico; Urban, David; Beoletto, Paolo H.; Torgersen, Jan; Pugno, Nicola M.; Gliozzi, Antonio S. (Peer reviewed; Journal article, 2023)The cochlea has long been the subject of investigation in various research fields due to its intriguing spiral architecture and unique sensing characteristics. One of its most interesting features is tonotopy, the ability ... -
High-concentration wide-angle tracking integration with stacked lens arrays
Johnsen, Håkon Jarand Dugstad; Aksnes, Astrid; Torgersen, Jan (Chapter, 2019)Tracking-integration can reduce or eliminate the need for external solar tracking in CPV (concentrator photovoltaics). Previous research has shown how tracking-integrated systems can achieve high concentration ratios, wide ... -
High-performance stationary solar tracking through multi-objective optimization of beam-steering lens arrays
Johnsen, Håkon Jarand Dugstad; Aksnes, Astrid; Torgersen, Jan (Peer reviewed; Journal article, 2020)Beam-steering lens arrays enable solar tracking using millimeter-scale relative translation between a set of lens arrays. This may represent a promising alternative to the mechanical bulk of conventional solar trackers, ... -
Polarization-driven reversible actuation in a photo-responsive polymer composite
Urban, David; Marcucci, Niccolò; Wölfle, Christoph Hubertus; Torgersen, Jan; Hjelme, Dag Roar; Descrovi, Emiliano (Peer reviewed; Journal article, 2023)Light-responsive polymers and especially amorphous azopolymers with intrinsic anisotropic and polarization-dependent deformation photo-response hold great promises for remotely controlled, tunable devices. However, dynamic ... -
Pushing the limits of beam-steering lens arrays
Johnsen, Håkon Jarand Dugstad; Aksnes, Astrid; Torgersen, Jan (Journal article; Peer reviewed, 2019)An essential part of a concentrated solar power system is the solar tracker. Tracking is usually implemented by rotating the entire optical system to follow the sun, adding to the bulk and complexity of the system. ...
