PROBLEM TO BE SOLVED: To solve the following problem: conventionally, a solar cell module having photoelectric conversion elements arranged in one direction and connected in series to each other has been generally used; however, under a status where the distribution of light volume of irradiated light is large, for example, in an indoor use, electric energy output from an optical power generation device decreases significantly because an output current of the optical power generation device is limited to an electric current of the photoelectric conversion element meeting a portion with a small quantity of light.SOLUTION: The optical power generation device includes: a first photoelectric conversion element row formed by electrically connecting a plurality of photoelectric conversion elements in series; a second photoelectric conversion element row formed by electrically connecting a plurality of photoelectric conversion elements in such a direction as to cross the serial connection direction. The first photoelectric conversion element row and the second photoelectric conversion element row are connected in parallel to each other.SELECTED DRAWING: Figure 1 |
