NOVELTY - The interconnector (20) has a band-shaped conductive metal including a first surface and a second surface opposite to the first surface. A solder (23) is coated on the first surface. The first surface of the conductive metal includes a flattened peak extending along a length direction of the conductive metal. The flattened peak includes an inclined portion and a flat portion extending in a width direction of the conductive metal, where length of the inclined portion is less than length of the flat portion in the width direction of the conductive metal.    USE - Interconnector for a solar cell module (claimed) for electrically connecting multiple solar cells of the solar cell module.    ADVANTAGE - The interconnector ensures that a back surface field region serves as a potential barrier of a substrate to prevent or reduce a recombination and/or disappearance of electrons and holes at and around the back surface of the substrate, so that efficiency of the solar cell is improved. The interconnector ensures that a first surface of a second area comprises a flat surface, such that an amount of the solder positioned between a first bus bar electrode and the first surface with the flat surface is more than an amount of the solder positioned between a second bus bar electrode and the first surface not comprising the flat surface, so that the adhesion strength between the second bus bar electrode and the interconnector can be increased. The second surface of the interconnector is attached to the front electrode part of the solar cell, where light is scattered by the uneven surface of the first surface opposite to the second surface, so that the amount of light incident on the solar cell can be increased.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a solar cell module.    DESCRIPTION OF DRAWING(S) - The drawing shows a side view of an electrical connection structure of solar cells.
