  • Electrospinning device
    Patent number: 9469920
    Abstract: The present invention relates to an electrospinning device. The electrospinning device may apply the force of a supersonic flow acting at a predetermined angle with respect to an electrostatic force on a fiber discharged from an electrospinning nozzle to cause shearing stress on the fiber, thereby providing fibers having a very small diameter and collecting fibers having a finer diameter. Also, the electrospinning device may collect finer and more uniform fibers by adjusting the relative positions of the electrospinning nozzle for discharging the fiber and a gas spray nozzle for spraying a gas.
    Type: Grant

  • Apparatus for manufacturing an inorganic thin-film solar cell, and method for controlling same
    Patent number: 9401449
    Abstract: The present invention relates to an apparatus for manufacturing an inorganic thin-film solar cell, the apparatus including: a substrate stage which is mounted in a chamber and in which a solar cell substrate is disposed; and an inorganic powder supply unit including a nozzle configured to discharge an inorganic powder aerosol containing an inorganic powder onto the substrate stage in a supersonic flow so as to form a solar cell layer on the solar cell substrate, and an inorganic powder supply portion configured to supply the inorganic powder aerosol to the nozzle.
