A Universal Urbach Rule for Disordered Organic Semiconductors
Christina Kaiser, Oskar J. Sandberg, Nasim Zarrabi +3
In crystalline semiconductors, absorption onset sharpness is characterized by temperature dependent Urbach energies. These energies quantify the static, structural disorder causing…

Determining Ultra-low Absorption Coefficients of Organic Semiconductors from the Sub-bandgap Photovoltaic External Quantum Efficiency
Christina Kaiser, Stefan Zeiske, Paul Meredith +1
Energy states below the bandgap of a semiconductor, such as trap states or charge transfer states in organic donor acceptor blends, can contribute to light absorption. Due to their…
