Since the display layer 2 is positioned on the light receiving surface (front surface) side of the solar cell panel 40, that is, so as to cover the light receiving surface, from the viewpoint of power generation efficiency of the solar cell panel 40, the display layer 2 is as transparent as possible, that is, high light. It preferably has transparency. The light transmittance of the display layer 2 varies depending on the displayed information, pattern, etc., but the display layer 2 preferably has a light transmittance such that the average transmittance is 20% or more, for example, 50% or more. It is more preferable to have a light transmission property, more preferably 70% or more. In addition, the information, the pattern, and the like displayed on the display surface 2A may or may not have light transmittance. However, considering power generation, it is preferable to have light transmittance.

  Here, the average transmittance in this specification means the visible light transmittance in the in-plane average of the display layer 2. As the value of the visible light transmittance, for example, using a SM color computer SM-C (manufactured by Suga Test Instruments Co., Ltd.), a visible light wavelength region of 380 nm to 750 nm is measured, and measurement of 12 samples collected arbitrarily It is preferable from the viewpoint of accuracy improvement to adopt a value obtained by averaging the values. In addition, when there is a place where the visible light transmittance is greatly different in the surface of the display layer 2, such as when information or a pattern displayed on the display layer 2 is formed, a place with a relatively large occupied area is selected. It is sufficient to pick and adopt the average of them. Note that a lens or a prism may be further provided on the display layer 2 having optical transparency. For example, the display layer 2 may be formed of a colored layer, a base material layer, and a prism or a lens.
