NOVELTY - The module has a battery piece whose surface is arranged on a P-electrode and P-type doped layer. An electric connecting layer is provided with multiple electric conduction wires. An insulation wire and the electric conduction wires are fixed together through a knitting part i.e. network-shaped structure. The electric conduction wires, the P-electrode and an N-electrode are electrically connected with each other. Diameter and width of a neighboring point are 0.4-1.5 mm. A linear electrode is made of silver paste, electric conduction glue and soldering tin materials.    USE - High efficiency main grid-less back contact solar energy battery module.    ADVANTAGE - The module prevents the P-electrode and N-electrode from being damaged. The module has low production cost and high efficiency, and can improve stability without using a main grate in a convenient manner.    DETAILED DESCRIPTION - The electric conduction wires are made of copper, aluminum, steel, copper and copper-clad steel materials. Cross sections of the electric conduction wires are in circular, square and elliptic-shape. The insulation wire is made of resin, rubber, silicon rubber and PVC materials. The electric conduction wires are plated with a protecting oxidation coating material that is made of tin, tin lead alloy and tin bismuth alloy materials. The electric conduction wires are provided with an electric conduction glue layer i.e. low resistance electric conduction adhesive glue. The electric conduction glue layer is arranged in an electric conduction particle layer that is made of gold, silver, copper and gold nickel materials. The electric conduction particle layer is made or silver-plated nickel and silver plated copper materials. The electric conduction particle layer is in spherical, sheet and olivary-shape. The electric conduction glue layer is arranged in a polymer adhesive layer that is epoxy resin, polyurethane resin, acrylic resin and organic silicon resin materials. The P-electrode and N-electrode are fixed with an insulation layer that is made of thermoplastic resin and thermosetting resin materials. The battery piece is provided with a resin layer e.g. ethylene-acetic acid ethylene copolymer, polyolefin resin, epoxy resin, polyurethane resin, acrylic resin and organic silicon resin. INDEPENDENT CLAIMS are also included for the following:    (1) a high efficiency main grid-less back contact solar energy battery component    (2) a high efficiency main grid-less back contact solar energy battery module manufacturing method.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a high efficiency main grid-less back contact solar energy battery module.
