Methodology to analyse small silicon samples by glow discharge mass spectroscopy using thin wafer mask
Modanese, Chiara; Arnberg, Lars; Di Sabatino, Marisa (Peer reviewed; Journal article, 2015)Glow discharge mass spectrometry (GDMS) is widely used for trace element analysis of bulk solid samples. Thegeometry of the GD source limits the minimum size of the sample, which for the instrument used in this ... -
Modeling and performance analysis of a solar photovoltaic energy community in Norway
Greciano Zamorano, Andrés (Master thesis, 2023)De høye strømprisene, fallende kostnader for installasjon av solenergi og de store forventningene om at solenergi, sammen med vindenergi, skal være de viktigste veiene for å nå det europeiske målet om netto nullutslipp ... -
N-type Czochralski silicon ingots - Oxygen-related defects in the last solid fraction
Haave, Bjørn (Master thesis, 2016)The focus of this master's thesis has been the formation of oxygen-related defects in the last 10 cm before the tail in Czochralski silicon ingots for solar cell applications. For nine industrial standard ingots from ... -
N-type Czochralski silicon solidification: Oxygen- and copper-related defects formation
Gaspar, Guilherme Manuel Morais (Doctoral thesis at NTNU;2016:68, Doctoral thesis, 2016)This PhD work was focused on the formation of oxygen- and copper-related defects in ntype Czochralski silicon for solar cells. These defects are a very important source of material and solar cell performance degradation, ... -
Nucleation and growth of multicrystalline silicon
Undheim, Espen (Doctoral theses at NTNU;2018:42, Doctoral thesis, 2018)This work has focused on the nucleation process of multicrystalline silicon (mc-Si) for photovoltaic (PV) applications during solidification in α-Si3N4 coated crucibles, the typical crucible coating used commercially. ... -
Oxygen and related defects in Czochralski silicon crowns
Pascoa, Soraia Sofia (Master thesis, 2014)For the purpose of this thesis work, four n-type CZ silicon ingots with different crown tapered angle and shouldering area were characterized in order to understand the oxygen behavior and related defects on ingot top cuts ... -
Phosphorus modification in Al-Si hypereutectic alloys
Zambon, Alessio (Master thesis, 2016)We wanted to know how the primary silicon is influeced by the modification with phoshorus. Some analysis with light microscope were done in order to see how the particles change with the phosphorus modification. Also the ... -
Properties of multicrystalline silicon wafers and case study of PV module viability analysis
Zickus, Simonas (Master thesis, 2017)Multicrystalline silicon solar cells are becoming a major stream technology. The main reason is the increase of efficiency of solar cells and constant production costs decline. In some countries PV can directly compete ... -
The role of silicon nitride crucible materials on silicon ingots contamination
Ferreira Dias, Goncalo Rafael (Master thesis, 2017)This work focuses on the characterisation of the solid diffusion mechanism of iron and titanium impurities in a silicon nitride crucible, as a substitute for silica crucibles currently used for solar cells production. This ... -
Study and investigation of oxygen related defects in Czochralski silicon ingots
Warden, Gabriela Kazimiera (Master thesis, 2020)Etter hvert som oppmerksomheten mot klimakrisen har økt de siste arene, har også interessen for bedre ytelse til grønne energikilder økt. Et eksempel på slike energikilder er monokrystallinske silisium solceller, for hvilke ... -
Study of a modified AA2618 wrought aluminum alloy to enhance thermal resistance - For automotive applications
Balducci, Eleonora (Master thesis, 2015)Aluminum alloys exhibit a huge potential due to their strength-to-weight ratio and therefore play a key role as regards achieving the desired mass reduction in the automotive field. Their main limit is the loss of strength ... -
Temperature-dependent carrier lifetime measurements on silicon wafers and bricks
Kristiansson, Vilma Helena Erika (Master thesis, 2023)Dette arbeidet presenterer en ny metode for å måle temperaturavhengig ladninsbærer levetid i krystallinske silisium wafere, bricks og ingots. Det eksperimentelle oppsettet består av en BCT-300 ladningsbærer levetidsmåler ... -
The effect of Zr and V on the structural and mechanical properties of the 2618 Al alloy
Zappi, Eleonora (Master thesis, 2014)During the last decades, the use of aluminium components for automotive applications has continuously increased. The main reason for this success is the high strength-to-weight ratio which characterizes these alloys, and ...
