Structural and Vibrational Properties of C60 Fullerene Thin Films on Gold Surfaces — •Caroline Henneke, Philip Schulz, Tobias Schäfer, and Matthias Wuttig — I. Physikalisches Institut (IA), RWTH Aachen University, Germany
The fullerene C60 is a widely employed acceptor material for organic solar cells. By tailoring the structure of C60 thin films and thus tuning their properties the efficiency of C60-based solar cells can be improved. However, it remains a main challenge to determine the correlation between the structure of C60 thin films and their optoelectronic properties.
Here, the influence of substrate temperature during deposition in a vacuum thermal evaporation process (VTE) on the structure and vibrational properties of C60 thin films on Au surfaces is investigated. Substrate temperatures ranging from 150 K to 700 K were applied in this study. XRD measurements were conducted to identify structural changes in the C60 thin films, while the surface morphology was determined by AFM measurements. The vibrational characteristics of the C60 thin films were investigated by Fourier-Transform Infrared spectroscopy (FTIR).
