The structural and electronic properties of lead phthalocyanine thin films on single crystal diamond

Abstract

This work investigates the use of diamond as a part of a solar cell. As the earth’s population is rising, the demand for energy is also rising. With the growth of countries like China, there is a need for new solutions. The goal is to see if diamond can helps with these issues. For several years, diamond has been getting more attention as a possible candidate in solar cells. The main focus has been on the use of diamond in combination with organic dyes, other molecules and polymers. The interface between the diamond substrate and the organic layer will determine the charge transfer between the layers. Therefore it is important to understand the influence of the diamond surface on the deposited layer. In the case of diamond, the properties of the surface can be altered. It can be terminated with a variety of atoms. In this work, hydrogen and oxygen termination will be used. This changes the surface from hydrophobic in the hydrogen terminated case to hydrophylic in the oxygen terminated case. The main question to be answered is what the influence of the termination of the diamond surface is on the growth, structure and opto-electronic properties of deposited organic layers....
