Bathocuproine (BCP, C26H20N2), 99%, 3g

Bathocuproine (BCP) is the most popular electron transport material due to its wide-band-gap and high electron affinity. A thin layer of BCP inserted between a metal cathode and an electron transport layer improves the performances of organic light emitting diodes and organic photovoltaic cells (including perovskite solar cells) significantly. BCP has a large ionization energy of 6.5 eV, which is the highest occupied molecular orbital derived-level (HOMO level) with respect to the vacuum level and corresponds to the hole transport level. Thus, the BCP layer was initially intended to block the exciton and hole diffusion from the electron transport layer to the cathode.
