SOLAR CELL, METHOD FOR PRODUCING SAME, AND SOLAR CELL MODULE

摘要

The present invention is provided with: a semiconductor substrate (11) having a first conductivity type and having an impurity diffusion layer (3) wherein an impurity element of a second conductivity type has been diffused in one surface side thereof; a light-receiving-surface-side electrode (5) formed on one surface side of the semiconductor substrate (11) and electrically connected to the impurity diffusion layer (3); and a rear-surface-side electrode (7) formed on the other surface side of the semiconductor substrate (11). The surface of the other surface side of the semiconductor substrate (11) has a first bumpy shape (2a), at least a portion of the surface of the one surface side of the semiconductor substrate (11) has a second bumpy shape (2b) that has a light reflectance that is lower than that of the first bumpy shape (2a), and thus the light reflectance of the one surface side of the semiconductor substrate (11) is lower than the light reflectance of the other surface side of the semiconductor substrate (11).
