Abstract: A solar cell includes: a first bus bar electrode disposed on a first end portion of the solar cell, and to which the wiring member is connected; a second bus bar electrode disposed on a second end portion of the solar cell, and to which the wiring member is connected; first finger electrodes disposed on the solar cell, electrically connected to the first bus bar electrode, and extending in a first direction toward the second bus bar electrode; second finger electrodes disposed on the solar cell, electrically connected to the second bus bar electrode, and extending in a second direction toward the first bus bar electrode. Each first finger electrode has a thickness which decreases as a distance to the second bus bar electrode decreases, and each second finger electrode has a thickness which decreases as a distance to the first bus bar electrode decreases.
