In order to improve the efficiency of a solar cell system, compaction (improvement of a light received density) of a solar cell module and directive (dependence characteristic of a solar position) reduction are tried. In this study, the optimum arrangement of the solar cell module with plant leaf shape is investigated. Therefore, in this paper, the difference in light receiving density of square leaf and of the ginkgo was clarified by numerical simulation, and the optimal solution of each shoot shape and the results of the light received density were obtained. As a result, the light receiving density of the leaf of ginkgo is 2.5 times as the leaf of the square in the sunshine of summer solstice conditions, and 1.6 times as the leaf of the square in the sunshine of winter solstice conditions. It is predicted that a light received density increases by plant leaf shape.
