1. A solar cell comprising:
a first substrate;
a second substrate;
a third substrate;
a first photoelectric conversion layer;
a second photoelectric conversion layer; and
a pair of electrodes,
wherein the first substrate and the second substrate have light-transmitting properties,
wherein the second substrate is disposed between the first substrate and the third substrate,
wherein the first photoelectric conversion layer is disposed between the first substrate and the second substrate,
wherein the second photoelectric conversion layer is disposed between the second substrate and the third substrate,
wherein the pair of electrodes are disposed so as to sandwich the first photoelectric conversion layer therebetween in a direction perpendicular to an arrangement direction of the first substrate, the second substrate, and the third substrate,
wherein the pair of electrodes cause an electric current to flow in the direction perpendicular to the arrangement direction of the first substrate, the second substrate, and the third substrate, and wherein
each of the pair of electrodes is defined by a single rectangular shape in cross-sectional view.
