Application of 7N In as secondary cathode for the direct current-glow discharge mass spectrometry analysis of solid, fused high-purity quartz
Busam, Jochen; Stokkan, Gaute; Muggerud, Astrid Marie F; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2021)Direct current glow discharge mass spectrometry with an indium-based secondary cathode technique is used to analyze solid, nonconducting, fused high-purity quartz regarding metallic impurities of relevance to the solar ... -
The effect of preliminary heat treatment on the durability of reaction bonded silicon nitride crucibles for solar cells applications
Hendawi, Rania Tayseer Atieh; Ciftja, Arjan; Stokkan, Gaute; Arnberg, Lars; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2020)Silicon nitride crucibles have the potential to replace silica crucibles and reduce the cost of silicon crystallization because of their reusability potential. Till date, crucibles’ heat treatment before each use is a ... -
Guidelines for establishing an etching procedure for dislocation density measurements on multicrystalline silicon samples
Adamczyk, Krzysztof Jan; Stokkan, Gaute; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2018)With multicrystalline silicon becoming the main material used for photovoltaic applications and dislocations being one of the main material limitations to better solar cell efficiency, etch pit density measurements are ... -
High performance multicrystalline silicon: Grain structure and iron precipitation
Autruffe, Antoine; M'hamdi, Mohammed; Schindler, Florian; Heinz, Friedemann D.; Ekstrøm, Kai Erik; Schubert, Martin C.; Di Sabatino Lundberg, Marisa; Stokkan, Gaute (Peer reviewed; Journal article, 2017)A study of the spatial occurrence of iron precipitation in a high performance multicrystalline silicon (HPMC-Si) sample is presented. The separated effects of grain-boundaries, sparse intra-granular dislocations, and ... -
Novel technique to study the wet chemical etching response of multi-crystalline silicon wafers
Matkivskyi, Vladyslav; Røyset, Arne Karstein; Stokkan, Gaute; Tetlie, Pål; Sabatino, Marisa Di; Tranell, Gabriella (Peer reviewed; Journal article, 2022)The current work aimed to demonstrate the application of a technique where white light interferometry (WLI) and Laue X-ray crystallography scanner characterisation were combined to study the chemical etching response of ... -
Recombination activity of grain boundaries in high-performance multicrystalline Si during solar cell processing
Krzysztof, Adamczyk; Søndenå, Rune; Stokkan, Gaute; Looney, Erin; Jensen, Mallory; Lai, Barry; Rinio, Markus; Sabatino, Marisa Di (Journal article; Peer reviewed, 2018)In this work, we applied internal quantum efficiency mapping to study the recombination activity of grain boundaries in High Performance Multicrystalline Silicon under different processing conditions. Wafers were divided ... -
Silicon powder-based wafers for low-cost photovoltaics: Laser treatments and nanowire etching
Jia, Guobin; Plentz, Jonathan; Gawlik, Annett; S. Azar, Amin; Stokkan, Gaute; Syvertsen, Martin; Almeida Carvalho, Patricia; Dellith, Jan; Dellith, Andrea; Andrä, Gudrun; Ulyashin, Alexander (Peer reviewed; Journal article, 2018)In this study, laser-treated polycrystalline Si (pc-Si) wafers, fabricated by wire sawing of hot-pressed ingots sintered from Si powder, have been investigated. As-cut wafers and those with high-quality thin Si layers ...
