Composition And Conductor Formed Therefrom

摘要

A composition comprises a metal powder. The composition further comprises a solder powder which has a lower melting temperature than a melting temperature of the metal powder. The composition further comprises a polymer and a carboxylated-polymer different from the polymer. The carboxylated-polymer is useful for fluxing the metal powder and cross-linking the polymer. The composition further comprises a dicarboxylic acid and a monocarboxylic acid. The acids are useful for fluxing the metal powder. The composition may be used for forming a conductor. The conductor may be used for current trans and/or electrical connection. An article comprises a substrate and the conductor disposed on and in electrical contact with the substrate. The article may be used for various applications, such as for converting light of many different wavelengths into electricity. Examples of such articles include photovoltaic (PV) cells and circuit boards.
