Solar cell module

摘要

A solar cell module includes: two solar cells, each including: a first main face and a second main face; a first electrode on the first main face, comprising a bus-bar electrode having at least one of an opening portion, notch portion, and gap portion; and a second electrode on the first or second main face having a polarity opposite to that of the first electrode; a wiring member that electrically connects the first electrode of one solar cell to the second electrode of another solar cell; and an electrically conductive connection layer that contacts the wiring member and the first main face.

1. A solar cell module, comprising:
two solar cells, each including:
a semiconductor photo-electric conversion body having a first main face and a second main face;a first electrode on the first main face, the first electrode comprising a bus-bar electrode having one or more opening portions through the bus-bar electrode, the bus-bar electrode directly contacting the first main face; anda second electrode on the second main face having a polarity opposite to that of the first electrode; a wiring member that electrically connects the first electrode of one solar cell to the second electrode of another solar cell; and wherein each of the two solar cells further includes an electrically conductive connection layer that contacts the wiring member and extends continuously across each of the one or more opening portions, the electrically conductive connection layer being in direct contact with the first main face that is exposed at each of the one or more opening portions, wherein in each of the two solar cells: the first electrode further comprises a plurality of finger electrodes with a constant spacing between adjacent finger electrodes, and an opening portion length of each of the one or more opening portions in a longitudinal direction of the wiring member is smaller than the constant spacing between adjacent finger electrodes.
