Bathocuproin

Описание

Organic photovoltaic cells (OPVCs) are considered to be promising devices because of their mechanical flexibility, ease of fabrication and potential for low-cost production. For small-molecule OPVCs the most-common material to use between the acceptor, here C60, and the top electrode, Al, is 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline, also known as bathocuproine. Indeed, the insertion of BCP results in an enhanced power-conversion efficiency (PCE). The improved power-conversion efficiency has been attributed to an increased exciton harvesting in the active layer. As BCP is a wide-band-gap material it acts as an exciton-blocking barrier (EBL) that prohibits excitons diffusing towards the Al electrode where they would otherwise be quenched.

Yellow powder

Использование

Bathocuproine can be used as an electron-modifying layer or as an interlayer between ETLs (electron transport layers) in calcite solar cells, and it can be prepared by spin-coating deposition or vacuum thermal evaporation. The addition of Bathocuproine enhances the energy conversion efficiency of organic photovoltaic cells.
