An electrical connection is formed between first and second conductive elements, by inserting a nano-metal material between the first and second conductive elements; and heating the nano-metal material to a melting temperature to form the electrical connection between the first and second conductive elements. The nano-metal material may comprise a nano-metal paste or ink comprised of one or more of Gold (Au), Copper (Cu), Silver (Ag), and/or Aluminum (Al) nano-particles that melt or fuse into a solid to form the electrical connection, at a melting temperature of about 150-250 degrees C., and more preferably, about 175-225 degrees C. The electrical connection may be formed between a solar cell and a substrate by creating a via in the solar cell between a front and back side of the solar cell, wherein the via is connected to a contact on the front side of the solar cell and a trace on the substrate.
