| 摘要 |
This invention relates to a transparent flat body including two transparent cover layers ( 1, 2 ) that confine between them an active layer ( 3 ) whose transparency varies in an electric field and disposed between two electrode layers ( 6, 7 ) optionally subdivided into sections, and a photovoltaic element that is connected to two electrode layers ( 6, 8 ), preferably via a control stage ( 11 ), and that includes a photoactive layer ( 4 ) between the two electrode layers ( 6, 8 ) of the photovoltaic element ( 5 ), characterized in that the photoactive layer ( 4 ) is made of two transparent molecular components in a manner known per se, one of the two electrode layers ( 6, 7 ) of the active layer ( 3 ) is simultaneously one of the two electrode layers ( 6, 8 ) of the photovoltaic element ( 5 ), and the two transparent cover layers ( 1, 2 ) confine between them both the photovoltaic element ( 5 ) and the active layer ( 3 ).
