Zero-dimensional and one-dimensional nanostructured materials for application in photovoltaic cells

Abstract

Zero-dimensional materials such as quantum dots and one-dimensional materials such as nanorods and nanowires have attracted significant attention in the past two decades and have been demonstrated as important building blocks for numerous electronic and optoelectronic device applications. Of course, the starting place for the field is the ability to grow various nanomaterials in different morphologies. In this thesis, we have demonstrated successful synthesis of both quantum dots and nanowires belonging to a totally new material class and have subsequently utilized them for photovoltaic cells in different device architectures. Apart from the photovoltaic cells, we have demonstrated a scalable way to fabricate carbon nanotube devices with a high on-off ratio on a wafer scale.
