    • A solar cell with integrated bypass function includes: a first conductivity type substrate 1 selected from P-type and N-type substrates; a region 2 of a second conductivity type which is opposite to the first conductivity type, the region 2 being formed on a light receiving side of the substrate; at least one third region 4 of the first conductivity type, having a higher dopant impurity concentration than the substrate 1 and being formed in a portion of the light receiving side of the substrate 1 so as to be in contact with both the substrate 1 and the region 2 of the second conductivity type; an insulator film 9 formed on at least a part of the at least one third region 4; and a light receiving side electrode 7 formed on the insulator film 9 so as to be in partial contact with the region 2 of the second conductivity type.
    • 具有集成旁路功能的太阳能电池包括:选自P型和N型衬底的第一导电型衬底1; 与第一导电类型相反的第二导电类型的区域2,区域2形成在基板的光接收侧; 第一导电类型的至少一个第三区域4具有比衬底1更高的掺杂剂杂质浓度并且形成在衬底1的光接收侧的一部分中以与衬底1和 第二导电类型的区域2; 形成在所述至少一个第三区域4的至少一部分上的绝缘膜9; 以及形成在绝缘膜9上以与第二导电类型的区域2部分接触的光接收侧电极7。
