NOVELTY - A conductive paste comprises a conductive powder, a metallic glass, and an organic vehicle, where the metallic glass has a resistivity that decreases more than that of the metallic glass before heat treatment when the metallic glass is heat treated at a temperature that is higher than a glass transition temperature of the metallic glass.    USE - As conductive paste used in an electronic device and a solar cell (claimed).    ADVANTAGE - The paste is capable of improving conductivity of an electrode. The metallic glass has a lower resistivity and an improved conductivity after the heat treatment because the element with the highest conductivity, or its alloy, of the components of the metallic glass is the first crystallized component of the component elements of the metallic glass. The solar cell including both of the first electrode and the second electrode on the rear surface of the solar cell may decrease an area where a metal is disposed on the front surface. This decreases shadowing loss and increases solar cell efficiency.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) an electronic device comprising, an electrode comprising a product of a conductive paste comprising a conductive powder, a metallic glass, and an organic vehicle, where the metallic glass has a resistivity that decreases more than that of the metallic glass before heat treatment when the metallic glass is heat treated at a temperature that is higher than a glass transition temperature of the metallic glass;    (2) a solar cell comprising, a semiconductor layer, and an electrode electrically connected with the semiconductor layer and comprising a fired conductive paste comprising a conductive powder, a metallic glass, and an organic vehicle, where the metallic glass has a resistivity that decreases more than that of the metallic glass before heat treatment when the metallic glass is heat treated at a temperature that is higher than a glass transition temperature of the metallic glass.
