Abstract
The invention relates to an illumination device (1000) comprising an at least partially transparent solar cell (200) that is arranged at the back side of an at least partially transparent light source (100). Preferably, the light source (100) is an OLED that is structured into a plurality of electroluminescent zones (131) and inactive zones (132). The electroluminescent zones are preferably aligned with reflective zones (311) of a mirror layer (310) that is disposed between the light source (100) and the solar cell (200).
