Abstract

In this work, we have used the Pattern Replication in Non-wetting Templates (PRINT®) technique to pattern both titania and cadmium selenide (CdSe) quantum dots for potential application in hybrid photovoltaic devices. Titania lines have been replicated from an E-beam fabricated line grating master that consists of lines that are 60 nm in width, 100 nm in height, and spaced by 60 nm. Additionally we have extended the PRINT process to include the ability to pattern CdSe quantum dots. Patterns in this material have been generated using a master that consists of cylinders that are 200 nm in diameter and 200 nm in height. We have also demonstrated the ability to conformally coat these inorganic structures with a conjugated polymer film, indicating the possibility for these patterns to be-used in hybrid photovoltaic devices.
