Organic Solar Cells

Abstract

Organic solar cells attract both scientific and economic interest due to their potential for clean and cost-effective photovoltaic energy conversion. Continuous evolution of this field relies on materials research, including synthesis of new compounds and fine control over film microstructure, as well as improved device architectures. In this context, spectroscopic ellipsometry is a helpful characterization tool, stretching over material preparation, device structure, and device modelling. This chapter will provide a general perspective of aspects that can be investigated by ellipsometry in these systems. The acquired insights enhance our capability to understand and model the optoelectronic properties of photovoltaic devices.
