SOLAR BATTERY CELL, SOLAR BATTERY MODULE, AND SOLAR BATTERY MODULE MANUFACTURING METHOD

摘要

A solar battery cell comprises: a substrate; a plurality of finger electrodes formed on the light receiving surface of the substrate; and a back side electrode sufficiently covering the back side of the substrate and connected to the finger electrodes on an adjacent cell by bonding a first TAB wire through a conductive adhesive. The back side electrode has an omitted portion arranged so as to define at least one alignment mark indicating a position at which the first TAB wire is bonded, and the at least one alignment mark has a width smaller than the width of the first TAB wire.
