  • Patent number: 8916412
    Abstract: A method of forming an ohmic contact and electron reflector on a surface of a CdTe containing compound film as may be found, for example in a photovoltaic cell. The method comprises forming a Cd-deficient, Te-rich surface region at a surface of the CdTe containing compound film; exposing the Cd-deficient surface region to an electron reflector forming material; forming the electron reflector; and laying down a contact layer over the electron reflector layer. The solar cell so produced has a Cd-deficient region which is converted to an electron reflector layer on the surface of a CdTe absorber layer, and an ohmic contact. A Cd/Te molar ratio within the Cd-deficient region decreases from 1 at an interface with the CdTe absorber layer to a value less than 1 towards the ohmic contact.

  • Patent number: 8912625
    Abstract: Device structures with a reduced junction area in an SOI process, methods of making the device structures, and design structures for a lateral diode. The device structure includes one or more dielectric regions, such as STI regions, positioned in the device region and intersecting the p-n junction between an anode and cathode. The dielectric regions, which may be formed using shallow trench isolation techniques, function to reduce the width of a p-n junction with respect to the width area of the cathode at a location spaced laterally from the p-n junction and the anode. The width difference and presence of the dielectric regions creates an asymmetrical diode structure. The volume of the device region occupied by the dielectric regions is minimized to preserve the volume of the cathode and anode.
