  • Patent number: 9944802
    Abstract: The present invention relates to a composition for forming a solar cell electrode, comprising: silver (Ag) powder; a glass frit comprising silver (Ag) and tellurium (Te) elements; and an organic vehicle, wherein the glass frit has a mole ratio of 1:01 to 1:25 of Ag to Te. The solar cell electrode produced from the composition has excellent fill factor and conversion efficiency as contact resistance (Rc) and series resistance (Rs) are minimized.

  • Patent number: 9911872
    Abstract: A composition for solar cell electrodes and electrodes fabricated using the same. The composition includes a silver (Ag) powder; a glass frit containing about 0.1 mole % to about 50 mole % of elemental silver; and an organic vehicle, wherein the elemental silver derives from a silver halide (Ag—X). The composition introduces a glass frit including a silver halide to enhance contact efficiency between electrodes and a silicon wafer, and solar cell electrodes prepared from the composition have minimized contact resistance (Rc), specific contact resistivity, and serial resistance (Rs), thereby exhibiting excellent conversion efficiency.
