The goal of this study was to characterize alloy nanoparticles with different bimetallic ratios of silver (Ag) and copper (Cu) by determining the composition and alloy structures. One specific objective was to determine how the composition affects the electrical properties of the nanoparticles in terms of electrical resistance and nanoparticle sintering. The desire for this study stems from the need to make conductive pastes for low-cost solar panel manufacturing. We performed experiments to develop the aqueous synthesis of core-shell bimetallic nanoparticles.
We investigated the room temperature sintering properties with the nanoparticles of varying compositions. The nanoparticles were characterized with several techniques, including UV- Visible spectroscopy, X-Ray diffraction, TEM and ICP. The resulting nanoparticles were used to fabricate conductive inks and pastes with varying formulations. The results will be discussed, along with the potential applications of nanomaterials.
