  • Publication number: 20210280735
    Abstract: Described herein is a diffusion-based ex-situ group V element doping method in the CdCl2 heat-treated polycrystalline CdTe film. The ex-situ doping using group V halides, such as PCl3, AsCl3, SbCl3, or BiCl3, demonstrated a promising PCE of ˜18% and long-term light soaking stability in CdSe/CdTe and CdS/CdTe devices with decent carrier concentration>1015 cm?3. This ex-situ solution or vapor process can provide a low-cost alternative pathway for effective doping of As, as well as P, Sb, and Bi, in CdTe solar cells with limited deviation from the current CdTe manufacturing process.

  • Patent number: 11102438
    Abstract: A two-by-two array consists of four pixels. Each pixel comprises one light-sensing transistor and one reading transistor. Both the light sensing transistor and the reading transistor are formed above a same P-type semiconductor substrate, and have a composite dielectric gate structure. The substrates of the four reading transistors are connected to form a regular octagonal ring structure located in the center of the array. On four sides of the regular octagonal ring structure, four heavily-doped N+ regions are formed on the substrates not covered with the composite dielectric gate, of which every two regions are opposite to each other and form right angles, wherein two opposite heavily-doped N+ regions are connected to form a shared N+ source, and the other two are connected to form a shared N+ drain.

  • Publication number: 20210209098
    Abstract: A system receives a source database language statement according to a first dialect, determines a pattern of the source database language statement, the pattern comprising an abstract representation of the source database language statement, and checks whether the determined pattern is present in a cache of translations between patterns according to the first dialect and corresponding patterns according to a second dialect different from the first dialect. In response to the determined pattern being present in the cache of translations, the system converts, using a corresponding translation in the cache of translations, the source database language statement according to the first dialect to a respective target database language statement according to the second dialect.

  • Patent number: 10986215
    Abstract: An approach for accessing one or more resources at a virtualized desktop infrastructure (VDI) client running on a client device by a remote virtual machine (VM) is provided. The method includes intercepting, via a VDI agent, a request to access one or more resources at the client device, transferring the request from the remote VM to the client device via a network redirector protocol, and filtering the request to determine if the request complies with one or more rules. For a first resource of the one or more resources, if the request does not comply with any one of one or more first rules of the one or more rules, access to the first resource is denied. If the request complies with the one or more first rules, access to the first resource is granted and a response is sent to the VDI agent via the network redirector protocol.

  • Patent number: 10868075
    Abstract: A photosensitive detection unit has a composite dielectric gate MOS-C portion and a composite dielectric gate MOSFET portion. The two portions are formed above a same P-type semiconductor substrate, and share a charge coupled layer. A plurality of the photosensitive detection units are arranged on a same P-type semiconductor substrate in form of an array to obtain a detector. Adjacent unit pixels in the detector are isolated by deep trench isolation regions and P+-type injection regions below the isolation regions. During the detection, the P-type semiconductor substrate in the composite dielectric gate MOS-C portion senses light and then couples photoelectrons to the charge coupled layer, and photoelectronic signals are read by the composite dielectric gate MOSFET portion.

  • Patent number: 10708349
    Abstract: A server offloads one or more tasks to a first media gateway. The server receives, from the first media gateway that is receiving a video stream of a television channel, a first message that indicates that the first media gateway is eligible to process a request for media content of the television channel that otherwise would be processed by the server. The server receives, from a second media gateway, a request for media content of the television channel. The server transmits, to the second media gateway, a redirection response that instructs the second media gateway to request the media content from the first media gateway.
