摘要： Disclosed is a photovoltaic module including a plurality of concentrators each having a light-incident plane and a reflection plane, and photo detectors. Each photo detector is in contact with one of the concentrators. The module is capable of effectively trapping light and effectively generating power throughout the year even if the module is established such that sunlight at the equinoxes is made incident on the light-incident planes not in a perpendicular manner but instead obliquely, for example, in the case where the module is established in contact with a curved plane of a roof, or the like. In this module, each concentrator is formed into such a shape as to satisfy a relationship in which the light trapping efficiency of first incident light tilted rightwardly from the normal line of the light-incident plane in the cross-section including the light-incident plane, reflection plane and photo detector is larger than the light trapping efficiency of second incident light tilted leftwardly from the normal line in the above cross-section. Also, these concentrators are arranged in one direction.

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.
