The invention relates to a sun-blind element with one or more horizontally and/or vertically and/or slantwise oriented lamellae (1) that are fixed or vertically and/or horizontally and/or slantwise movable and that can be pivoted about their longitudinal axis (2) at least to some extent or not at all. The lamella upper surface (3) and/or the lamella lower surface (4) is provided with at least one means (5) for generating an electric potential and/or an electric current by the incidence of light. The at least one lamella (1) substantially consists of one or several means (5) for generating an electric potential and/or an electric current by the incidence of light. |
