摘要

One approach used in modern devices for excitation of nerve tissues consists of wireless excitation, in which organic photosensitive materials convert light into electrical signals. Organic photocapacitors accumulate charge and transfer it to cells via capacitive coupling, reducing electrochemical side effects. Numerical simulation studies addressed the behavior of an organic semiconductor made of phthalocyanine and perylene tetracarbonyl diimide under the influence of incident light with a wavelength of 625 nm. The main subjects of attention were the processes of photon absorption, exciton generation, and exciton separation into free charge carriers, as well as the distribution of electric potential and charge transfer.
