Effect of gas atmospheres on the interactions between liquid silicon and coated graphite substrates
Hendawi, Rania; Arnberg, Lars; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2022)Interactions between the gas atmosphere, liquid silicon, Si3N4 coating, and graphite are of great interest for photovoltaic silicon applications. However, previous studies focus more on the wetting of silicon on coated ... -
Electrical properties and microstructure of crystalline silicon ingots grown from quartz crucibles with and without diffusion barriers
Søndenå, Rune; Stokkan, Gaute; Busam, Jochen Thilo; Hendawi, Rania; Hallam, Benny; Sabatino, Marisa Di (Chapter, 2023) -
Formation of Primary Silicon and its Influence on the Eutectic Solidification in Unmodified Hypoeutectic Al-Si Alloys - Investigation of Orientation Relationships by EBSD
Hendawi, Rania (Master thesis, 2018)Nucleation and growth of the primary and eutectic silicon in unmodified hypoeutectic Al-Si alloy have been investigated for via optical microscopy, EBSD and SEM . The influence of the cooling rate and phosphorus concentration ... -
Microstructure and electrical properties of multi- crystalline silicon ingots made in silicon nitride crucibles
Hendawi, Rania; Søndenå, Rune; Ciftja, Arjan; Stokkan, Gaute; Arnberg, Lars; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2022)Silicon nitride is a more sustainable crucible material than silica, due to the larger potential for re-use. In this work, two directionally solidified high-performance multi-crystalline silicon (HPMC-Si) ingots have been ... -
Reusable crucible materials and coatings for photovoltaic silicon applications
Hendawi, Rania (Doctoral theses at NTNU;2021:419, Doctoral thesis, 2021)Currently, more than 90% of commercial solar cells are made from crystalline silicon. The crystalline silicon materials are classified into two types: monocrystalline and multi-crystalline silicon. Multi-crystalline silicon ...
