    • A multi junction photovoltaic device and an integrated multi junction photovoltaic device, having a two-terminal structure, in which subsequent layers can be stacked under conditions with minimal restrictions imposed by previously stacked layers. Also, processes for producing these photovoltaic devices. A plurality of photovoltaic cells having different spectral sensitivity levels are stacked such that at least the photovoltaic cells (2, 4) at the light-incident end and the opposite end have a conductive thin-film layer (5a, 5d) as the outermost layer that undergoes connection, the remaining photovoltaic cell (3) has conductive thin-film layers (5b, 5c) as the outermost layers that undergo connection, and the outermost layers are bonded via anisotropic conductive adhesive layers (6a, 6b) containing conductive microparticles within a transparent insulating material. The conductive microparticles in the anisotropic conductive adhesive layers (6a, 6b) electrically connect the layers in the stacking direction, and the conductive thin film layers (5a, 5b, 5c, 5d) electrically connect the photovoltaic layers (2, 3, 4) that function as bonding materials in the lateral direction (in-plane direction).
    • 多结光伏器件和集成多结光伏器件,具有双端子结构,其中后续层可以在具有由先前堆叠的层施加的最小限制的条件下堆叠。 另外,制造这些光电器件的方法。 堆叠具有不同光谱灵敏度级别的多个光伏电池,使得至少在光入射端和相对端处的光伏电池(2,4)具有作为最外层的导电薄膜层(5a,5d) 其余的光伏电池(3)具有作为经历连接的最外层的导电薄膜层(5b,5c),并且最外层通过包含导电微粒的各向异性导电粘合剂层(6a,6b) 透明绝缘材料。 各向异性导电粘合剂层(6a,6b)中的导电性微粒在层叠方向上电连接,导电性薄膜层(5a,5b,5c,5d)将光电转换层(2,3,4) 在横向(面内方向)上起粘接材料的作用。
