Provided is a stacked multi-junction solar cell with a front side contacted through the rear side and having a solar cell stack having a Ge substrate layer, a Ge subcell, and at least two III-V subcells, with a through contact opening, a front terminal contact, a rear terminal contact, an antireflection layer formed on a part of the front side of the multi-junction solar cell, a dielectric insulating layer, and a contact layer. The dielectric insulating layer covers the antireflection layer, an edge region of a top of the front terminal contact, a lateral surface of the through contact opening, and a region of the rear side of the solar cell stack adjacent to the through contact opening. The contact layer from a region of the top of the front terminal contact that is not covered by the dielectric insulating layer through the through contact opening to the rear side. 提供一种具有背侧接通的正侧的堆叠状的多结太阳能电池，其具有包括锗衬底、锗子电池和至少两个III-V族子电池的太阳能电池堆叠，太阳能电池堆叠具有敷镀贯通开口、正侧连接接通部、背侧连接接通部、构造在多结太阳能电池的正侧的部分上的抗反射层、介电的隔离层以及接通层，其中，介电的隔离层覆盖抗反射层、
