Bathocuproine (BCP) is a wide-band-gap material and has a high electron affinity. When it is embedded into organic electronic devices, bathocuproine acts as an exciton-blocking barrier?which prohibits exciton diffusion process?towards the Al electrode otherwise being quenched. One of the most commonly used buffer layer between acceptor and cathode layers is?bathocuproine. The introduction of the buffer layer can greatly improve the PCE of polymer organic solar cells.?BCP is one of the most popular hole-blocking layer materials that is used in organic electronics, including perovskite solar cells.
Odor Light yellow powder
