PURPOSE: A photovoltaic power generation device is provided to improve photoelectric conversion efficiency by increasing the amount of light entering a solar cell through the reflective surface of a reflection part. CONSTITUTION: A substrate (100) includes a center region (CR) and an edge region (OR) surrounding the center region. A solar cell (C) is arranged in the center region of the substrate. A reflection part (200) is arranged in the edge region of the substrate. The reflection part changes the path of light emitted from the edge region in a lateral direction, an upper direction or a lower direction. The reflection part includes reflection patterns (210,220,230). The reflection patterns include a reflective surface inclined to the upper surface of the substrate. |
