Abstract: An efficient nanoscale semiconducting optoelectronic system, containing a P/N acceptor donor organic hetrojunction which is optimized for neuronal stimulation—an organic electrolytic photocapacitor. The devices comprise a thin (80 nm) trilayer of metal and p-n semiconducting organic nanocrystals. When illuminated in physiological solution, these metal-semiconductor devices charge up, transducing light pulses into localized displacement currents that are strong enough to electrically stimulate neurons with safe light intensities.

Abstract: 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).

Abstract: The invention relates to a transparent flat body comprising two transparent covering layers (1, 2) which enclose an active layer (3) between two electrode layers (6, 7) which are optionally divided into sections, the transparency of said active layer varying in an electric field, and a photovoltaic element (5) connected to the electrode layers (6, 7) preferably by at least one control stage (11) comprising a photoactive layer (4) between two electrode layers (6, 8). In order to provide a simple construction, the photoactive layer (4) of the photovoltaic element (5) is made from two transparent molecular components in a manner known per se, one of the two electrode layers (6, 7) of the active layer (3) is made from one of the electrode layers (6, 8) of the photovoltaic element (5) and both transparent covering layers (1, 2) enclose between the photovoltaic element (5) and the active layer (3).
