  • Patent number: 9001863
    Abstract: A graphite crucible for electromagnetic induction-based silicon melting and an apparatus for silicon melting/refining using the same, which performs a melting operation by a combination of indirect melting and direct melting. The crucible is formed of a graphite material and includes a cylindrical body having an open upper part through which a silicon raw material is charged into the crucible, and an outer wall surround by an induction coil, wherein a plurality of first slits are vertically formed through the outer wall and an inner wall of the crucible, and a plurality of second slits are vertically formed from an edge of the disc-shaped bottom of the crucible toward a center of the bottom.
    Type: Grant

  • Patent number: 8968470
    Abstract: Disclosed herein are a graphite crucible for electromagnetic induction-based silicon melting and an apparatus for silicon melting/refining using the same, which performs a melting operation by a combination of indirect melting and direct melting. The crucible is formed of a graphite material and includes a cylindrical body having an open upper part through which a silicon raw material is charged into the crucible, and an outer wall surrounded by an induction coil, wherein a plurality of slits are vertically formed through the outer wall and an inner wall of the crucible such that an electromagnetic force created by an electric current flowing in the induction coil acts toward an inner center of the crucible to prevent a silicon melt from contacting the inner wall of the crucible.

  • Publication number: 20080078440
    Abstract: Disclosed is an electric wire bracket for solar cells, which includes a pair of upper and lower plates respectively having adhesive layers adhered to each other and grooves facing each other so as to form insertion paths, into which a plurality of electric wires for supplying power produced by solar cells to electronic instruments are inserted, through the connection of the upper and lower plates by adhering the adhesive layers to each other, thus facilitating the connection of the wires. The electric wire bracket for solar cells includes a lower plate, an upper plate, release papers, and conductive layers, wherein at least one insertion path, into which the electric wires for solar cells are inserted, is formed by connecting the lower plate and the upper plate.
