SOLAR CELL AND METHOD FOR MANUFACTURING SAME

摘要

This solar cell is provided with: a semiconductor substrate (2) of a first conductivity type, which has, on one surface, an n-type impurity diffusion layer (3) wherein an impurity element of a second conductivity type is diffused; a light receiving surface-side electrode (12) which is formed on the one surface side of the semiconductor substrate (2) and is electrically connected to the n-type impurity diffusion layer (3); a back-side silver sputtering film (8) which is formed on a region of the other surface of the semiconductor substrate (2), has a light reflectance higher than an aluminum electrode that is formed from an aluminum paste, and reflects the light transmitted through the semiconductor substrate (2) from the one surface of the semiconductor substrate (2); and a conductive film (22) which serves as a connection layer for connecting a tab wire that electrically connects the other surface of the semiconductor substrate (2) and another solar cell (1) with each other, and which is bonded to a region of the other surface of the semiconductor substrate (2), said region being the region other than the back-side silver sputtering film (8).
