Summary:To provide a solar battery having a plurality of subcells connected by a metal wiring structure, and an individualization technique for forming a solar battery having a plurality of subcells connected by a metal wiring structure.SOLUTION: A solar battery 106 is singulated or diced to have subcells 108 and 110 that are physically separated from each other. Adjacent portions have a groove 112 therebetween and are filled with an encapsulating material 114. A monolithic metal wiring structure 116 is used as a backstop for separating the metal into individual cells, and couples the subcells together.SELECTED DRAWING: Figure 1B 【課題】金属配線構造体によって結合された複数のサブセルを有する太陽電池、および金属配線構造体によって結合された複数のサブセルを有する太陽電池を形成する個片化手法を提供する。【解決手段】太陽電池１０６は、互いに物理的に分離されたサブセル１０８および１１０を有する様に個片化またはダイシングされている。隣接する部分同士は、それらの間に溝１１２を有し、封入材料１１４で充填されている。モノリシック金属配線構造体１１６は金属をセル個片化のためのバックストップとして用いられるとともに、サブセル同士を結合する。【選択図】図１Ｂ
