Abstract

Organic double-heterostructure photovoltaic cells employing thick tris(acetylacetonato)ruthenium(III) exciton-blocking layers (EBL) are studied. Thick EBLs are practically important for fabricating large-area devices with a low density of electrical shorts. The EBL serves a number of functions, including preventing damage to the photoactive layer during cathode deposition and thereby eliminating exciton quenching at the acceptor/cathode interface. Doping, or using low-resistance compounds has proven to be a route to using thicker EBL layers.
