PROBLEM TO BE SOLVED: To provide a method for inexpensively forming a rear face structure of a solar cell having an excellent passivation performance, high adhesion and a high light reflection effect.SOLUTION: A solar cell manufacturing method comprises the steps of: introducing at least one of impurities expressing a second conductive type having a polarity electrically opposite to that of a substrate 101 into the substrate 101 to form a second conductive type region 102 on a light receiving plane of the crystal silicon substrate 101 having a first conductive type; forming a first dielectric film 103 at least partially covering the light receiving plane; forming a second dielectric film 107 at least partially covering a non light receiving plane; covering the second dielectric film 107 with a reflection film 108 made of metallic elements contained in the second dielectric film 107 as a main component; forming a first electrode 104 in contact with the second conductive type region 102; and forming the second electrode 109 in contact with the substrate 101. In the solar cell manufacturing method, the second dielectric film 107 and the reflection film 108 are continuously formed. |
