Application

Phen-NaDPO is a universal cathode modifier for organic optoelectronics. Phen-NaDPO can significantly lower the work function of the Ag metal as well as ITO and HOPG.
It lowers the energy loss between organic layer and the metal electrode, results in higher acheiveable efficiency for organic solar cells. It is also used as cathode interfacial material for inverted Perovskite solar cells, and electron transport materials for Perovskite solar cells and other organic electronic devices in general.
