Solar cell module and manufacturing method thereof

摘要

First cells 10, obtained by cutting each of disk-formed solar battery cells at cutting positions set in parallel on the main surface thereof symmetrically with respect to the center line which halves the main surface, are arranged in parallel and staggered manner to thereby fabricate a solar battery module 100. Also two segments of by-produced second cells 20 R and 20 L are paired so as to oppose both cut edges, and a plurality of thus-obtained pairs are arranged to thereby produce a solar battery module 101. This makes it possible to reduce loss of disk-formed wafers, and to raise the module-packing ratio higher than that in the case where the disk-formed cells are arranged in an intact form. This is successful in providing solar battery modules and a method of fabricating the same capable of raising the module-packing ratio while reducing the loss of single crystal wafer to be used.
