Abstract: A solar cell module comprises a solar cell element, first and second connection tabs, and first and second solder portions. The solar cell element includes a semiconductor substrate, a front busbar electrode, and a back busbar electrode. The first solder portion connects the front busbar electrode and the first connection tab. The second solder portion connects the back busbar electrode and the second connection tab. A distance between the first lateral surface and a first bonding surface where the first solder portion is bonded to the front busbar electrode is shorter than a distance between the first lateral surface and a second bonding surface where the second solder portion is bonded to the back busbar electrode. A distance between the second lateral surface and the first bonding surface is shorter than a distance between the second lateral surface and the second bonding surface.

Abstract: To improve the yield of a solar cell in its production process, a solar cell includes a semiconductor substrate including a first main surface and a second main surface corresponding to the backside of the first main surface, a busbar electrode on a line extending in a first direction on the second main surface, and end-portion electrodes each being an extension of the busbar electrode on the second main surface and separated from the busbar electrode, and each of the end-portion electrodes having a larger thickness than that of the busbar electrode.

Abstract: A solar cell is provided with: a semiconductor substrate having a main surface; a plurality of first electrodes disposed so as to be aligned in one direction on the main surface of the semiconductor substrate, the first electrodes having obverse and side surfaces; a passivation layer disposed on the main surface of the semiconductor substrate and positioned in the gaps between the first electrodes; a conductive adhesive disposed on the obverse surfaces of the first electrodes; and lead members connected to adjacent first electrodes by the conductive adhesive so as to straddle the passivation layer. The solar cell is further provided with contact members, the contact members being positioned in gaps, being disposed on the obverse surface of the passivation layer or the main surface of the semiconductor substrate in alignment with the passivation layer in one direction, and being in contact with parts of the lead members from underneath.
