General description

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Bathocuproine (BCP) supports more sustainable OLEDs as an electron-transport/exciton-blocking layer that can enable higher power efficiency, lower operating voltage, and longer device lifetimes reducing energy use and material waste across the product lifecycle.
