Today's most frequently used production path for polysilicon and solar grade silicon (SG-Si) is based on thermal decomposition of trichlorosilane (SiHCl 3 ) in a Siemens-type reactor. Due to the batch-wise mode of its operation and its requirement fo

There is a deficit of ways to detect higher order silane isomers during silane pyrolysis. Thus, a novel instrument utilizing gas chromatography-mass spectrometry (GC-MS) for detection of higher order silanes has been developed. The instrument enables

For an installed silicon-based solar cell panel, about 40% of the energy needed for fabrication is consumed for production of the silicon feedstock. Reducing the energy consumption in this step is therefore crucial in order to minimize the energy pay

Free-standing Pd/Ag23 wt% membranes with five different thicknesses ranging from ∼1.3 to ∼5.0 μm were prepared by magnetron sputtering. The hydrogen permeation was determined before and after a thermal treatment in air at 300 °C. For all membra
