Abstract:
1. A photovoltaic power generation module having a rectangular shape, the module comprising: arcuate cells divided from a disk-shaped single crystal silicon photovoltaic power generation cell, wherein the arcuate cells have a circular arc with a central angle of 90°, the arcuate cells have a grid perpendicular to a chord and at least one busbar perpendicular to the grid and parallel to the chord, the arcuate cells are arranged as a matrix so as to form a plurality of cell rows and a plurality of cell columns perpendicular thereto, the cell rows are formed by reversing the chord-to-arc direction of adjacent arcuate cells, the cell columns are formed so that the chord-to-arc directions of adjacent arcuate cells are the same, the arcuate cells are arrayed so that ends of arcuate cells forming one cell column enter respective recessed regions between adjacent cells forming the cell column adjacent to the above cell column, the arcuate cells have an area of 28 to 65 cm the arcuate cells have an auxiliary electrode extending from the busbar so as to intersect the grid within a region in which the grid provided on the arcuate cell does not intersect the busbar.
