Abstract
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.
