摘要：PROBLEM TO BE SOLVED: To provide a solar cell for increasing photoelectricconversion efficiency, by reducing contact resistance of the semiconductor and theelectrode, while increasing the amount of light entering into the solar cell, and to providea method of manufacturing a solar cell.SOLUTION: A solar cell includes an unevenstructure provided on the light receiving surface of a first conductivity type
semiconductor substrate 2, multiple salients 11 constituting the uneven structure, asecond conductivity type impurity diffusion layer 12 provided on the tip surface layer ofthe multiple salients 11, an electrode 14 having a metal material provided selectively onthe tip of some salients 11 out of the multiple salients 11, a metal containing layerformed on the second conductivity type impurity diffusion layer 12, and containing ametal material for electrically conducting the electrode 14 and second conductivity typeimpurity diffusion layer 12, and a conductor 15 provided on the electrode 14, andconnecting the electrodes 14 electrically.SELECTED DRAWING: Figure 1
