摘要： A solar cell for a solar cell array with one or more grid on a surface thereof, wherein electrical connections are made to the grids in a plurality of locations positioned around the solar cell; and the electrical connections extend to one or more conductors located under the solar cell. The conductors located under the solar cell are buried within a substrate, and each of the conductors comprises a low resistance conducting path that distributes current from the solar cell. The conductors are loops, U-shaped, or have only up or down pathways. The solar cell comprises a full cell that has four cropped corners and the locations are in the cropped corners.

摘要： 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.

摘要： A solar cell array is comprised of at least one solar cell and a substrate for the solar cell. The solar cell has at least one cropped corner that defines a corner region, wherein the corner region includes at least one contact for making an electrical connection to the solar cell. The contact comprises a front contact on a front side of the solar cell and/or a back contact on a back side of the solar cell, wherein the contact extends into the corner region. The solar cell is attached to the substrate such that corner regions of adjacent solar cells are aligned, thereby exposing an area of the substrate where electrical connections between the solar cells are made using corner conductors. The electrical connections are up/down and/or left/right series connections that determine a flow of current through the cells.
