  • Solar cell
    Patent number: 10074754
    Abstract: A solar cell, including a substrate; and an electrode on at least one surface of the substrate. The electrode may be prepared from an electrode paste including tungsten oxide particles, and the electrode may have an adhesive strength of about 4 N/mm to about 6 N/mm with respect to a ribbon for interconnecting solar cells, as measured under conditions of a peeling angle of 180° and a stretching rate of 50 mm/min.
    Type: Grant
    Filed: July 21, 2015
    Date of Patent: September 11, 2018
    Assignee: Samsung SDI Co., Ltd.
    Inventors: JuHee Kim, Dong Suk Kim, Seok Hyun Jung, Min Jae Kim, SeakCheol Kim, Sang Hyun Yang, Je Il Lee
  • Composition for solar cell electrode and electrode prepared using the same
    Patent number: 9997648
    Abstract: A composition for solar cell electrodes and a solar cell electrode, the composition including silver powder; glass frit that contains tellurium, the glass frit having a glass transition temperature (Tg) of about 150° C. to about 300° C.; an organosilane compound; and an organic vehicle.
    Type: Grant
    Filed: December 10, 2015
    Date of Patent: June 12, 2018
    Assignee: SAMSUNG SDI CO., LTD.
    Inventors: Seok Hyun Jung, Dong Suk Kim, JuHee Kim, Min Su Park, Min Jae Kim, SeakCheol Kim, Sang Hyun Yang, Je Il Lee
  • Composition for forming solar cell electrode and electrode produced from same
    Patent number: 9899545
    Abstract: A composition for solar cell electrodes and electrodes fabricated using the same. The composition includes silver powder; fumed silica; a glass frit; and an organic vehicle. The composition has improved contact efficiency between electrodes and a silicon wafer by introducing specific fumed silica. Solar cell electrodes fabricated using the composition exhibit minimized serial resistance, thereby providing excellent fill factor and conversion efficiency.
