Hydrogen Concentration in Photovoltaic a-Si:H Annealed at Different Temperatures Measured by Neutron Reflectometry
A. J. Qviller, E. S. Marstein, C. C. You +5
Amorphous hydrogenated silicon (a-Si:H) is an important material for surface defect passivation of photovoltaic silicon (Si) wafers in order to reduce their recombination losses. T…
New insights into the photochromic mechanism in oxygen-containing yttrium hydride thin films: an optical perspective
J. Montero, F. A. Martinsen, S. Zh. Karazhanov +2
Oxygen-containing yttrium hydride thin films exhibit a photochromic behavior: transparent thin films switch from a transparent state to a photodarkened state after being illuminate…
Vibrational zero point energy for H-doped Silicon
S. Zh. Karazhanov, M. Ganchenkova, E. S. Marstein
Most of the studies addressed to computations of hydrogen parameters in semiconductor systems, such as silicon, are performed at zero temperature T=0 K and do not account for contr…
Oxidation effects on graded porous silicon anti-reflection coatings
Annett Thøgersen, Josefine H. Selj, Erik S. Marstein
Efficient anti-reflection coatings (ARC) improve the light collection and thereby increase the current output of solar cells. By simple electrochemical etching of the Si wafer, por…
A new thin film photochromic material: Oxygen-containing yttrium hydride
Trygve Mongstad, Charlotte Platzer-Björkman, Jan Petter Maehlen +6
In this work we report on photochromism in transparent thin film samples of oxygen-containing yttrium hydride. Exposure to visible and ultraviolet (UV) light at moderate intensity…
