摘要： A method of fabricating a solar cell forms a large number of grooves on a first main surface of a p-type silicon single crystal substrate sliced out from a silicon single crystal ingot as described below. First an edge portion of a groove-carving blade is projected out from a flat substrate feeding surface of a working table by a predetermined height. The p-type silicon single crystal substrate is moved along the substrate feeding surface towards the rotating groove-carving blade while keeping a close contact of the first main surface thereof with the substrate feeding surface. Electrodes are then formed on the inner side face of thus-carved grooves only on one side in the width-wise direction 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 20R and 20L 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.

摘要： A solar cell 1 has a number of grooves 2 formed in parallel with each other on a first main surface 24a of a silicon single crystal substrate. An electrode 6 is formed on the inner side face of each groove 2 on one side. Each groove 2 is formed in the direction in disagreement with the direction on the first main surface 24a. This raises mechanical strength of the solar cell 1. The direction of formation of the grooves 2 preferably crosses the direction nearest to the direction of formation at an angle of 4°˜45° on the acute angle side.
