Solar cell and solar cell module

摘要

A solar cell module includes first and second solar cells and an interconnector (IC) for electrically connecting the first and second solar cells. The first solar cell (Cell-a) and the second solar cell (Cell-b) each include a plurality of first electrodes (C141) formed on a back surface of a semiconductor substrate, a plurality of second electrodes (C142) formed on the back surface of the semiconductor substrate, a first auxiliary electrode (P141) connected to the plurality of first electrodes, a second auxiliary electrode (P142) connected to the plurality of second electrodes, and an insulating member (200) positioned on back surfaces of the first auxiliary electrode and the second auxiliary electrode. Each of the first solar cell and the second solar cell is formed as an individual integrated type element by connecting one semiconductor substrate and one insulating member.
