| Abstract: | In this work,we prepare the conductive silver adhesive by using 90 wt.%silver powder with 10 wt.%epoxy matrix in order to produce a high-silver-content and high-performance conductive adhesive.We find silver nanoparticles would be produced by 0.025 mol/L KI solution surface treatment of the silver powder under an in situ chemical reaction between the surface lubricant and the oxidized silver triggered by sunlight.These nano-sized silver particles are then sintered together on the surfaces of the silver micro-flakes and nano-particle balls in the silver powder during curing,which effectively increases the contact area between the adja-cent silver micro-flakes and nanoparticle balls,leading to decreasing electrical bulk resistivity and line resistance of the as-produced silver/epoxy conductive adhesive.Compared with the adhesive without KI surface treatment,our treated ones show 26%and 8%decrease in the electrical bulk resistivity and line resistance,respectively.It is applied to the photovoltaic panel to greatly improve its electrical conductivity. |
