Switchable absorber element and photovoltaic cell
The invention relates to a switchable absorber element and a photovoltaic cell based thereon. A switchable absorber element according to the invention has an absorber layer. The absorber element furthermore has at least one front side reflection layer and at least one rear side reflection layer, wherein the absorber layer is arranged between front side reflection layer and rear side reflection layer, wherein the optical path length between front side reflection layer and rear side reflection layer is less than 400 nm at least for light impinging perpendicularly onto the cell. The absorber element according to the invention is characterized in that at least one of the reflection layers has a switchable reflectivity.
