If it is too small, more solar cell devices have to be prepared in order to realize the desired amount of power generation, resulting in poor productivity. Further, the solar cell device of the present invention is preferably wound into a roll shape during transportation or storage, but if the surface area of the plastic foam on which the photoelectric conversion element is mounted is too large, the solar cell device may be wound into a roll shape. Becomes difficult. Therefore, the area of the surface mounting the photoelectric conversion element of the plastic foam, 25 cm 2 or more 40000Cm 2 more preferably in the range, 100 cm 2 or more 10000 cm 2 or less in the range is more preferable. The shape of the surface of the plastic foam to which the photoelectric conversion element is attached is preferably square or rectangular, but various shapes can be adopted for easy handling and for covering the water surface with as little space as possible.
