Abstrakt: Presents a study that determined the spatial dependence of the bulk free-carrier lifetime in cast polycrystalline silicon ingots from contactless measurements of optically modulated free-carrier infrared absorption. Information on unmodulated infrared probe transmission; Details on optically modulated infrared transmission measurements; Discussion on modulation factor versus pump wavelength, energy and depth.
