A TEM Study of Boron-implanted Cubic Silicon Carbide, for Solar Cell Applications
Hovden, Sigurd Slettemark (Master thesis, 2016)Recent research suggests that high doses of boron implantation can introduce an intermediate electron energy band in cubic silicon carbide (3C-SiC). This makes it a viable material for a highly efficient intermediate band ... -
Bifacial Solar Cells in Nordic Climate
Hansen, Siw Anita (Master thesis, 2018)Bifacial solar cells can be the new trend within photovoltaic (PV) technology. They have the ability to take advantage of not only the direct irradiance from the sunlight, but also the indirect light which is reflected by ... -
Diffusion studies of Fe in amorphous quartz for the PV industry
Austreid, Ragnhild (Master thesis, 2020)Kvartsdiglene som brukes til å støpe multikrystallinsk silisium (mc-Si) til solcelleindustrien er en dominerende forurensningskilde i silisiumproduksjonen. For høye konsentrasjoner av metalliske urenheter, som jern, i ... -
Effects of Shading on PV Power Production in Norwegian Climates
Willems, Carolyn Marie (Master thesis, 2018)Policy, and a significant decrease in cost have played a major role in bringing photovoltaic solar to the forefront as a renewable energy source and a lucrative business opportunity around the world. The Norwegian solar ... -
Electrical and structural properties of multicrystalline silicon grown from reusable silicon nitride crucibles
Martinsen, Kristoffer Harr (Master thesis, 2016)The solar cell industry has grown considerably and experiences renewed public interest due to technological advances and awareness of human impact on the environment. However, the industry faces several challenges that ... -
Electrical Characterization of Amorphous Silicon Nitride Passivation Layers for Crystalline Silicon Solar Cells
Helland, Susanne (Master thesis, 2011)High quality surface passivation is important for the reduction of recombination losses in solar cells. In this work, the passivation properties of amorphous hydrogenated silicon nitride for crystalline silicon solar cells ... -
Hot Pressing and Characterization of Powder Based Silicon Substrates for Photovoltaic Applications.
Juven, Phillip (Master thesis, 2012)High purity silicon material in solar cell fabrication constitutes 40% of the total cost for conventional solar cell production. One approach to reduce costs would be to use less of this expensive silicon by making thin ... -
Lifetime degradation in n-type Cz-Si
Koien, Vivian Sporstøl (Master thesis, 2012)The main object was to investigate the effect of donors, thermal donors and defects on the lifetime on n-type Czochralsky (Cz) silicon. Cz is a technique for making monocrystals by dipping a monocrystalline seed into the ... -
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, ... -
Numerical modelling of a Czochralski furnace with active cooling jacket - Optimization of quality and througput
Li, Zhengyu (Master thesis, 2015)In the single crystal silicon Czochlarski process, pull rate has a great impact on its production. More and more people put their eyes on optimizing the structure of Cz furnace to increase the pull rate, but experiments ... -
Optimization of the casting process for silicon nitride crucibles
Kanakakis, Ermis (Master thesis, 2017)As renewable energy sources get to replace conventional fossil fuel power plants, solar cells will come to play a major role. For this purpose, their efficiency must be enhanced and their cost minimized in order to compete ... -
Utvikling av metode for produksjon av cellulære mikrogranulater fra glassavfall
Andersen, Jonas Grov; Brendryen, Håkon; Leivseth, Eirik (Bachelor thesis, 2022)Formålet med oppgaven er å finne ett sett med prosessbetingelser for å ekspansjon av cellulære mikrogranulater i størrelsesområdet 20-90 μm i en vertikal ovn med en oppadgående gasstrøm. De cellulære mikrogranulatene skal ...
