    • Colloidal crystals as templates for light harvesting structures in solar cells 

      Haugan, Einar; Granlund, Håvard; Gjessing, Jo; Marstein, Erik Stensrud (Journal article; Peer reviewed, 2011)
      Monolayer colloidal crystals are formed using silica- and polystyrene beads and used as etch masks for the formation of regular, _m period hexagonal arrays of indentations in a silicon wafer. Such patterns can be used as ...

    • Development and Characterization of Surface Passivation Materials on Silicon Wafers for Solar Cells 

      Xuemei, Cheng (Doctoral theses at NTNU;2017:53, Doctoral thesis, 2017)
      A main challenge for high efficiency crystalline silicon solar cells is to reduce the current and voltage loss from the surface recombination process. An effective surface passivation system is needed to obtain high ...

    • Direct monitoring of minority carrier density during light induced degradation in Czochralski silicon by photoluminescence imaging 

      Nærland, Tine Uberg; Angelskår, Hallvard; Marstein, Erik Stensrud (Journal article; Peer reviewed, 2013)
      In this paper, we present a new method for studying the light induced degradation process, in which the minority carrier density is monitored directly during light soaking by photoluminescence imaging. We show experimentally ...

    • Energikrisen i Europa og det norske kraftmarkedet 

      Belsnes, Michael Martin; Bjørndal, Mette; Elverhøi, Anders; Espegren, Kari Aamodt; Fæhn, Taran; Jaehnert, Stefan; Kjølle, Gerd Hovin; Korpås, Magnus; Marstein, Erik Stensrud; Røkke, Petter Egil; Sandberg, Nina Holck; Tande, John Olav Giæver; Thiis, Thomas Kringlebotn; Winther, Tanja; Inderberg, Tor Håkon Jackson (NTNU Rapport 429810, Research report, 2023)
      Dette notatet oppsummerer en serie workshoper som ble organisert våren 2022 av FME-sentrene NTRANS, CINELDI, ZEN, HighEFF, Include, NorthWind og HydroCEN, sammen med NTVA og DNVA. Ved noen workshoper ble flere partnere ...

    • Innovasjonsarbeid i FME-ene, mars 2020 

      Gustavsen, Arild; Kvellheim, Ann Kristin; Medbø, Eirik Gjelsvik; Tomasgard, Asgeir; Coldevin, Grete Håkonsen; Kjølle, Gerd Hovin; Bergmann-Paulsen, Jonas; Brende, Hege; Claussen, Ingrid Camilla; Røkke, Petter Egil; Størset, Sigmund Østtveit; Mølnvik, Mona J.; Haug, Halvard; Marstein, Erik Stensrud (Research report, 2020)
      Fra innledningen. FME ZEN er et senter for miljøvennlig energi som skal utvikle løsninger for framtidens bygninger og byområder – løsninger som bidrar til at nullut-slippssamfunnet kan realiseres. FME ZEN skal vare i åtte ...

    • Limiting imbalance settlement costs from variable renewable energy sources in the Nordics: Internal balancing vs. balancing market participation 

      Klyve, Øyvind Sommer; Klæboe, Gro; Nygård, Magnus Moe; Marstein, Erik Stensrud (Peer reviewed; Journal article, 2023)
      Due to the market gate closures in the Nordic energy markets, producers with variable renewable energy (VRE) assets, e.g., PV and wind power plants, must forecast their production prior to delivery, leaving room for ...

    • Performance Modeling of Bifacial PV Power Plants in a Nordic Climate 

      Martinsen, Dina Christensen (Master thesis, 2022)
      Bifacial fotovoltaisk (PV) teknologi kan produsere energi fra begge sider av modulen, og kan dermed øke energitettheten ved å utnytte reflektert lys. Teknologien har også vist potensiale til å kunne redusere utjevnet ...

    • Studying light-induced degradation by lifetime decay analysis: Excellent fit to solution of simple second-order rate equation 

      Nærland, Tine Uberg; Haug, Halvard; Angelskår, Hallvard; Søndenå, Rune; Marstein, Erik Stensrud; Arnberg, Lars (Journal article; Peer reviewed, 2013)
      Twenty different boron-doped Czochralski silicon materials have been analyzed for light-induced degradation. The carrier lifetime degradation was monitored by an automated quasi-steady-state photoconductance setup with an ...

    • Surface passivation properties of HfO2 thin film on n-Type crystalline Si 

      Cheng, Xuemei; Repo, Paivikki; Haug, Halvard; Perros, Alexander Pyymaki; Marstein, Erik Stensrud; Di Sabatino Lundberg, Marisa; Savin, Hele (Journal article, 2017)
      Atomic layer deposited hafnium oxide is shown to provide good surface passivation of low resistivity, n-type crystalline Si wafers after a low temperature anneal. The surface passivation is related to a fixed negative ...

    • Temporal stability of a-Si:H and a-SiNx:H on crystalline silicon wafers 

      Cheng, Xuemei; Marstein, Erik Stensrud; You, Chang Chuan; Haug, Halvard; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2017)
      The temporal stability of single layer thin films of hydrogenated amorphous silicon (a-Si:H) and silicon nitride (a-SiNx:H) passivated crystalline silicon wafers have been investigated over 18 months. The thin films were ...
