    • A solar cell includes a substrate, a lower conductor layer, an anti-reflection coating (ARC) layer and an upper conductor layer. The substrate has a front side, a back side and a doped region adjacent to the front side. The lower conductor layer has a first portion embedded into the doped region and a second portion other than the first portion. The ARC layer is disposed on the front side of the substrate and covers the lower conductor layer such that the second portion of the lower conductor layer is disposed in the ARC layer. The upper conductor layer has a first portion embedded into the ARC layer and a second portion other than the first portion of the upper conductor layer. The second portion of the upper conductor layer is exposed out of the ARC layer, and the upper conductor layer is electrically connected to the lower conductor layer.
    • 太阳能电池包括基板,下导体层,抗反射涂层(ARC)层和上导体层。 衬底具有与前侧相邻的前侧,后侧和掺杂区。 下导体层具有嵌入掺杂区域中的第一部分和除第一部分之外的第二部分。 ARC层设置在基板的前侧,并覆盖下导体层,使得下导体层的第二部分设置在ARC层中。 上导体层具有嵌入到ARC层中的第一部分和除了上导体层的第一部分之外的第二部分。 上导体层的第二部分露出ARC层,并且上导体层电连接到下导体层。
