    • A solar cell comprises a substrate that includes a photoelectric conversion function, a first electrode provided on one surface of the substrate, a second electrode provided on other surface of the substrate, and a third electrode provided on the other surface of the substrate with its periphery overlapping the second electrode in the in-plane direction of the substrate for extracting an electric power from the second electrode. The thickness of the second electrode is larger than that of the third electrode, and the difference between the thickness of the second electrode and that of the third electrode is within a range from equal to or more than 10 micrometers to equal to or less than 30 micrometers. Thereby, in the solar cell, an electrode separation (alloy separation) can be effectively prevented.
    • 一种太阳能电池包括:包含光电转换功能的基板,设置在基板的一个表面上的第一电极,设置在该基板的另一个表面上的第二电极;以及设置在基板的另一个表面上的第三电极, 在所述基板的面内方向上重叠所述第二电极,以从所述第二电极提取电力。 第二电极的厚度大于第三电极的厚度,并且第二电极的厚度与第三电极的厚度之间的差在等于或大于10微米至等于或小于30的范围内 微米。 因此,在太阳能电池中,能够有效地防止电极分离(合金分离)。
