NOVELTY - A light transmissible solar cell module (1) comprises: solar cell units, which comprise a transparent substrate (2), a mirror electrode layer (3) provided on one surface of multiple projecting portions of a transparent substrate comprising multiple projecting portions with a saw edge-like cross-section formed by connecting projecting portions having a first surface and a second surface that intersects with the first surface, and a solar cell section (4) provided on the mirror electrode layer.    USE - The light transmissible solar cell module is useful for providing illumination in buildings and establishments, and for generating power.    ADVANTAGE - The light transmissible solar cell module is suitable for installation on a window of a building, a ceiling that can take in outside light, and the like. Also, the module provide light transmissible solar cells having superior light transmissibility and excellent power generating efficiency.    DETAILED DESCRIPTION - A light transmissible solar cell module (1) comprises: solar cell units, which comprise a transparent substrate (2), a mirror electrode layer (3) provided on one surface of multiple projecting portions of a transparent substrate comprising multiple projecting portions with a saw edge-like cross-section formed by connecting projecting portions having a first surface and a second surface that intersects with the first surface, and a solar cell section (4) provided on the mirror electrode layer, arranged in multi-levels; a first connecting wire (10) electrically connected to an electrode (9) provided on a surface side of the solar cell section; and a second connecting wire electrically connected to the mirror electrode layer, where the solar cell units are arranged so that a light (7, 8) entering from one side hits the solar cell section of an arbitrary solar cell unit (12) and is reflected, and the reflected light reaches another side by being reflected by the mirror electrode layer of a solar cell unit arranged adjacent to the arbitrary solar cell unit. INDEPENDENT CLAIMS are:    (1) a solar cell panel formed by fixing light transmissible solar cell modules in a casing; and    (2) a process for manufacturing the light transmissible solar cell module, comprising: forming the mirror electrode layer by forming the metallic material as the film on one surface of multiple projecting portions of the transparent substrate comprising multiple projecting portions with the saw edge-like cross-section formed by connecting projecting portions having the first surface and the second surface that intersects with the first surface; forming the solar cell section by forming the semi-conductor material as the film on the mirror electrode layer; and obtaining the light transmissible solar cell module by forming the first connecting wire electrically connected with the electrode provided on the surface side of the solar cell section and the second connecting wire electrically connected to the mirror electrode layer.
