    Abstract: The present invention provides strategies for improving the quality of the insulating layer in MIS and SIS devices in which the insulator layer interfaces with at least one pnictide-containing film. The principles of the present invention are based at least in part on the discovery that very thin (20 nm or less) insulating films comprising a chalcogenide such as i-ZnS are surprisingly superior tunnel barriers in MIS and SIS devices incorporating pnictide semiconductors. In one aspect, the present invention relates to a photovoltaic device, comprising: a semiconductor region comprising at least one pnictide semiconductor; an insulating region electrically coupled to the semiconductor region, wherein the insulating region comprises at least one chalcogenide and has a thickness in the range from 0.5 nm to 20 nm; and a rectifying region electrically coupled to the semiconductor region in a manner such that the insulating region is electrically interposed between the collector region and the semiconductor region.
