  • Publication number: 20200357939
    Abstract: The present invention pertains to photodetectors based on colloidal quantum dot films. An ultrathin layer of metal oxide deposited at the heterojunction interface by atomic layer deposition (ALD) results in quantum dot infrared photodetectors with increased photocurrent, decreased dark current, and world-record specific detectivity of >2×1012 Jones for 2000-2550 nm at room temperature and zero applied bias. This detectivity is an order of magnitude higher than the detectivity of commercial detectors and better than any previously-published nanomaterial. In addition to record sensitivity, the devices of the present invention have large linear dynamic range (>120 dB) and good speed (39 kHz). The device fabrication is amenable to making detector arrays at the wafer scale. It has been shown that the thin metal oxide interlayer passivates interfacial defect states, which results in the lower dark current and improved photocurrent at zero bias.

  • Publication number: 20200350713
    Abstract: A power supply device includes a power supply housing having an accommodating space and an accommodating opening, a hybrid wire-to-wire connector structure and a circuit board disposed in the accommodating space. The hybrid wire-to-wire connector structure includes a connecting seat and an adapter seat. The connecting seat has a signal line terminal and a power line terminal. The connecting seat is disposed in the accommodating opening through an annular rib. The adapter seat has a signal conduction end and a power conduction end. The adapter seat has formed a hook corresponding to the annular rib. The connecting seat and the adapter seat are combined through the signal conduction end inserted in the signal line terminal, the power conduction end inserted in the power line terminal and the hook clamped with the annular rib. Therefore, the power and signal connectors are integrated so as to simplify the assembly.

  • Publication number: 20200335814
    Abstract: A ceramic-polymer film includes a polymer matrix; a plasticizer; a lithium salt; and AlxLi7-xLa3Zr1.75Ta0.25O12 where x ranges from 0.01 to 1 (LLZO), wherein the LLZO are nanoparticles with diameters that range from 20 to 2000 nm and wherein the film has an ionic conductivity of greater than 1×10?3 S/cm at room temperature. The nanocomposite film can be formed on a substrate and the concentration of LLZO nanoparticles decreases in the direction of the substrate to form a concentration gradient over the thickness of the film. The film can be employed as a non-flammable, solid-state electrolyte for lithium electrochemical cells and batteries. The LLZO serves as a barrier to dendrite growth.

  • Publication number: 20200176789
    Abstract: Molten carbonate fuel cells (MCFCs) are operated to provide enhanced CO2 utilization. This can increase the effective amount of carbonate ion transport that is achieved. The enhanced CO2 utilization is enabled in part by operating an MCFC under conditions that cause transport of alternative ions across the electrolyte. The amount of alternative ion transport that occurs during enhanced CO2 utilization can be mitigated by using a more acidic electrolyte.

  • Publication number: 20200176787
    Abstract: Molten carbonate fuel cell configurations are provided that include one or more baffle structures within the cathode gas collection volume. The baffle structures can reduce the unblocked flow cross-section of the cathode gas collection volume by 10% to 80%.
