<p>A solar cell device comprising a photovoltaically active layer between a transparent front cover and a back cover, wherein the front cover comprises a first surface region and a second surface region opposite thereto and facing the photovoltaically active layer, and the back cover comprises a third surface region facing the photovoltaically active layer and a fourth surface region opposite thereto, wherein at least one of the first to the fourth surface regions is provided with a first area and a second area, which areas have different light modulation properties, wherein both areas are light transparent, and wherein the solar cell device further comprises at least one light source (7) for coupling light laterally into at least one of the front cover (2) and the back cover (3). Moreover a method for producing such solar cell device, and an information board comprising such a solar cell device and its use for displaying information. (Fig. 2)</p> |
