Abstract:
To provide a solar cell having improved photoelectric conversion efficiency and a solar cell module. A solar cell (10) is provided with a photoelectric conversion portion (20), a light receiving surface electrode (21a) and a back surface electrode (21b). The light receiving surface electrode (21a) is arranged on the light receiving surface (20a) of the photoelectric conversion portion (20). The back surface electrode (21b) is arranged on the back surface (20b) of the photoelectric conversion portion (20). The back surface electrode (21b) includes metal film (21b1) and an electrical connection electrode (21b2). The metal film (21b1) at least partially covers the back surface (20b). The electrical connection electrode (21b2) is arranged on the metal film (21b1).
