Problem addressed: how to decrease the loss of visual quality in an image that appears when this image is placed behind a semitransparent photovoltaic sheet or film. Solution: on the one hand, increase the luminosity of the image by depositing a white-coloured or metallic or reflective layer on the side of the photovoltaic cells that is turned towards the image; and on the other hand, by modifying the luminosity, the contrast, and the colour saturation of the image. |
