<p>A solar battery cell (101) includes a plurality of grid electrodes (2) that are formed in parallel and bus bar electrodes (3) that are formed while extending on straight lines that are substantially orthogonal to the grid electrodes (2) and are connected to tab wires (5), on a light receiving surface of a silicon substrate (1), and also includes silver electrodes (7) that are connected to tab wires (8), on a back surface of the silicon substrate (1). The silver electrodes (7) are formed in a dot shape at a predetermined distance therebetween on straight lines that are opposite to the bus bar electrodes (3) while sandwiching the silicon substrate (1) together with the bus bar electrodes (3). The bus bar electrodes (3) are intermittently formed such that positions where the bus bar electrodes (3) are opposite to the silver electrodes (7) while sandwiching the silicon substrate (1) are missing. Because the bus bar electrodes (3) and the silver electrodes (7) are not overlapped with each other while sandwiching the silicon substrate (1), concentration of stress can be relaxed.</p> |
