Abstract: In a solar cell in a sheet form, a first cured resin layer, a substrate containing a resin, a photoelectric conversion layer, and a second cured resin layer are stacked in this order. The linear expansion coefficient of the first cured resin layer is not less than that of the second cured resin layer, and the linear expansion coefficient of the second cured resin layer is larger than that of the substrate. When the cure degree of a first surface of the first cured resin layer facing the substrate is C1 % and the cure degree of a second surface of the first cured resin layer is C2 %, C2 is larger than C1 and (C2−C1) is 2 to 15%. A surface on the first cured resin layer of the solar cell is warped convexly and a surface on the second cured resin layer is warped concavely.

Abstract: To provide a solar cell capable of being connected to a substrate using an FPC connector. A solar cell includes: a power generation layer formed on a surface of a base film; a sealing resin layer covering the power generation layer; a protective insulating layer covering an invalid area of the power generation layer; and terminal electrodes provided at positions overlapping the invalid area and at which voltage generated by a valid area of the power generation layer appears. With this configuration, even if cracks occur in the power generation layer upon connection to an FPC connector, the valid area will not be broken. In addition, the invalid area is covered with the protective insulating layer having an elasticity higher than that of the sealing resin layer, so that shock upon connection to the FPC connector is mitigated.
