Disclosed is a conductive paste including; a conductive powder including a plurality of conductive particles, a metallic glass disposed between adjacent conductive particles of the conductive powder, and an organic vehicle in which the conductive powder and metallic glass are disposed, and a solar cell using the conductive paste.

Conductive paste and solar cell

A conductive paste including a conductive powder, a metallic glass, and an organic vehicle, wherein the metallic glass has a resistivity that is decreased when the metallic glass is heat treated at a temperature that is higher than a glass transition temperature of the metallic glass.

Conductive paste and electronic device and solar cell including an electrode formed using the conductive paste

According to an example embodiment, a conductive paste includes a conductive powder, a metallic glass having a supercooled liquid region, and an organic vehicle. The metallic glass may include an alloy having a disordered atomic structure that includes at least two metals. An electronic device and/or solar cell may include an electrode formed using the conductive paste. An electrode formed using a conductive paste according to example embodiments may have lower contact resistance than an electrode formed using a conductive paste that includes glass frits instead of a metallic glass.

A conductive paste including a conductive powder, a metallic glass, and an organic vehicle, wherein the metallic glass includes an alloy of at least two elements selected from an element having a low resistivity, an element which forms a solid solution with the conductive powder, or an element having a high oxidation potential, wherein the element having a low resistivity has a resistivity of less than about 100 microohm-centimeters, and the element having a high oxidation potential has an absolute value of a Gibbs free energy of oxide formation of about 100 kiloJoules per mole or greater.
