Journal ArticleDOI
Vacuum Refining of Molten Silicon
Jafar Safarian,Merete Tangstad +1 more
TL;DR: In this paper, a novel mass transfer model for the removal of volatile impurities from silicon in vacuum induction refining is developed, and the boundary conditions for vacuum refining system are determined through thermodynamic and kinetic approaches.
Journal ArticleDOI
Processes for Upgrading Metallurgical Grade Silicon to Solar Grade Silicon
TL;DR: In this paper, the effect of impurities on the solar cell efficiencies and the impurity contents in silicon materials are studied and the chemical and metallurgical processes that can be applied to purify and upgrade MG-Si to solar grade silicon are reviewed and evaluated.
Journal ArticleDOI
Vacuum Evaporation of Pure Metals
TL;DR: In this paper, the authors reviewed and applied theories on the evaporation of pure substances and applied the Hertz-Knudsen equation for weak and intensive conditions, respectively, and showed that there is good agreement between different theories for weak, whereas there are differences under intensive conditions.
Journal ArticleDOI
Thermodynamic and Kinetic Behavior of B and Na Through the Contact of B-Doped Silicon with Na2O-SiO2 Slags
TL;DR: In this paper, it is shown that Boron removal from liquid silicon by sodium-silicate slags is experimentally studied and it is indicated that B can be rapidly removed within short reaction times.

TL;DR: The AMADEUS project as mentioned in this paper developed a new generation of phase change materials with latent heat in the range of 1000-2000 kWh/m3, an order of magnitude greater than that of typical salt-based PCMs used in concentrated solar power (CSP), along with developing advanced thermal insulation, PCM casing designs, and novel solid-state heat-to-power conversion technologies able to operate at temperatures between 1000 and 2000 °C.
