Abstract

Organic photovoltaic devices with compound charge transport layers are described herein. One such device includes a substrate, a first electrode coupled to the substrate, a second electrode disposed above the first electrode, and photoactive layers disposed between the first electrode and the second electrode. The device further includes a compound charge transport layer disposed between the photoactive layers and either the first electrode or the second electrode. The compound charge transport layer includes a charge transport layer and a metal-oxide interlayer disposed between the charge transport layer and the photoactive layers. The charge transport layer may be a hole transport layer or an electron transport layer.
