Abstract
Concentrations of monochlorosilane (SiH3Cl) of the order of 2500 ppm have been detected in some commercial tanks of silane by mass spectrometry and optical emission spectroscopy (OES). This impurity is shown to depress the position of the Fermi level in a-Si:H, resulting in lower photoconductivity and solar cell efficiency.
