Solution Approach 1:

The patent applies asymmetry by arranging photoelectric conversion bodies with non-uniform spacing in the first direction, where different photoelectric conversion bodies have different dimensions in the first direction. This asymmetric arrangement optimizes light absorption paths and reduces shading effects, thereby improving electric power generation efficiency while maintaining a relatively simple manufacturing process

AI summary

A photovoltaic power generation system includes first and second structures. The first structure includes first photoelectric conversion bodies aligned in a first direction at a first spacing and each extending in a second direction as a length direction of the first photoelectric conversion body. The second structure includes second photoelectric conversion bodies aligned in the first direction at a second spacing and each extending in the second direction as the length direction of the second photoelectric conversion body. The system satisfies at least one of a first requirement and a second requirement. The first requirement is that dimensions of the first photoelectric conversion bodies in the first direction is different from dimensions of the second photoelectric conversion bodies in the first direction. The second requirement is that the first spacing between the first photoelectric conversion bodies is different from the second spacing between the second photoelectric conversion bodies.
