Patent number: 9287435Abstract: The present invention uses a treatment that involves an etching treatment that forms a pnictogen-rich region on the surface of a pnictide semiconductor film The region is very thin in many modes of practice, often being on the order of only 2 to 3 nm thick in many embodiments. Previous investigators have left the region in place without appreciating the fact of its presence and/or that its presence, if known, can compromise electronic performance of resultant devices. The present invention appreciates that the formation and removal of the region advantageously renders the pnictide film surface highly smooth with reduced electronic defects. The surface is well-prepared for further device fabrication.Type: GrantFiled: January 30, 2013Date of Patent: March 15, 2016Assignees: Dow Global Technologies LLC, California Institute of TechnologyInventors: Gregory M.

Publication number: 20160071994Abstract: The principles of the present invention are used to reduce the conduction band offset between chalcogenide emitter and pnictide absorber films. Alternatively stated, the present invention provides strategies to more closely match the electron affinity characteristics between the absorber and emitter components. The resultant photovoltaic devices have the potential to have higher efficiency and higher open circuit voltage. The resistance of the resultant junctions would be lower with reduced current leakage. In illustrative modes of practice, the present invention incorporates one or more tuning agents into the emitter layer in order to adjust the electron affinity characteristics, thereby reducing the conduction band offset between the emitter and the absorber.Type: ApplicationFiled: January 30, 2013Publication date: March 10, 2016Inventors: Jeffrey P.

Publication number: 20150255637Abstract: 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.Type: ApplicationFiled: October 7, 2013Publication date: September 10, 2015Inventors: Jeffrey P.

Patent number: 9034685Abstract: The present invention provides methods for making pnictide compositions, particularly photoactive and/or semiconductive pnictides. In many embodiments, these compositions are in the form of thin films grown on a wide range of suitable substrates to be incorporated into a wide range of microelectronic devices, including photovoltaic devices, photodetectors, light emitting diodes, betavoltaic devices, thermoelectric devices, transistors, other optoelectronic devices, and the like. As an overview, the present invention prepares these compositions from suitable source compounds in which a vapor flux is derived from a source compound in a first processing zone, the vapor flux is treated in a second processing zone distinct from the first processing zone, and then the treated vapor flux, optionally in combination with one or more other ingredients, is used to grow pnictide films on a suitable substrate.Type: GrantFiled: February 10, 2012Date of Patent: May 19, 2015Assignees: Dow Global Technologies LLC, California Institute of TechnologyInventors: Gregory M.

Publication number: 20140360566Abstract: The present invention provides methods of making photovoltaic devices incorporating improved pnictide semiconductor films. In particular, the principles of the present invention are used to improve the surface quality of pnictide films. Photovoltaic devices incorporating these films demonstrate improved electronic performance. As an overview, the present invention involves a methodology that metalizes the pnictide film, anneals the metalized film under conditions that tend to form an alloy between the pnictide film and the alloy, and then removes the excess metal and at least a portion of the alloy. In one mode of practice, the pnictide semiconductor is Zinc phosphide and the metal is Magnesium.Type: ApplicationFiled: January 30, 2013Publication date: December 11, 2014Inventors: Gregory M.
