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.

Composition for forming solar cell electrode and electrode produced from same

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&#x2014;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.

Composition for forming electrode of solar cell, and electrode manufactured using same

A composition for solar cell electrodes, a solar cell electrode prepared from the composition, a solar cell, and a method of manufacturing the same, the composition including silver powder; silver iodide; glass frit; and an organic vehicle, wherein the silver iodide is present in an amount of about 0.1 wt % to about 30 wt %, based on a total weight of the composition.

Composition for solar cell electrodes and electrode fabricated using the same

A composition for solar cell electrodes includes a conductive powder, a glass frit, an organic vehicle and a thixotropic agent, and has a first thixotropic index (TI I) of about 1.5 to about 4 as represented by the following Equation 1, and a second thixotropic index (TI II) of about 4 to about 8 as represented by the following Equation 2, both the first thixotropic index and the second thixotropic index being measured at 23&#xb0; C. by a rotary viscometer. [Equation 1] TI I=(viscosity at 1 rpm/viscosity at 10 rpm) [Equation 2] TI II=(viscosity at 10 rpm/viscosity at 100 rpm).

A paste composition for solar cell electrodes includes a conductive powder, a glass frit, and an organic vehicle. The glass fit includes about 5 wt % to about 55 wt % of BiO, about 10 wt % to about 40 wt % of TeO, and a balance of PbO.
