Abstract

Although both valence and conduction bands play an important role in photogeneration of charge carriers and charge carrier separation in organic solar cells, only limited knowledge of the conduction bands of organic materials is available due to the low durability of the organic samples. In this study a new inverse-photoemission spectroscopy with zero-kinetic energy electrons will be developed aiming at a high energy resolution and low sample damage.
