  • Photo active layer by silicon quantum dot and the fabrication method thereof
    Patent number: 9425336
    Abstract: Provided is a photo active layer for a solar cell or a light emitting diode and a fabricating method thereof. The photo active layer is formed by alternately stacking silicon quantum dot layers in which a plurality of silicon quantum dots containing conductive type impurities are formed in a medium, which is a silicon compound, and conductive layers, which are polycrystalline silicon layers, containing the same conductive type impurities as those of the silicon quantum dots.
    Type: Grant
    Filed: March 22, 2012
    Date of Patent: August 23, 2016
    Assignee: Korea Research Institute of Standards and Science
    Inventors: Kyoung Joong Kim, Seung Hui Hong, Jae Hee Park, Jong Shik Jang
