Morphology control of CuPc thin films using Glancing Angle Deposition

Abstract

We present the use of Glancing Angle Deposition (GLAD) as a means to fabricate porous thin films of copper phthalocyanine (CuPc) with high surface area for use in bulk heterojunction (BHJ) organic photovoltaic (OPV) devices. The deposition parameters available in GLAD enable the manipulation of film morphology, and therefore the ability to optimize structuring for use in OPV devices. Feature sizes of CuPc films fabricated via GLAD are on the order required for an optimal BHJ structure. Initial devices have been fabricated with basic device architecture, representing a starting point from which device optimization can be performed.
