Quantifying the Excitonic Static Disorder in Organic Semiconductors
Austin M. Kay, Oskar J. Sandberg, Nasim Zarrabi +5
Organic semiconductors are disordered molecular solids and as a result, their internal charge dynamics and ultimately, the performance of the optoelectronic devices they constitute…
A quasi steady-state measurement of exciton diffusion lengths in organic semiconductors
Drew B. Riley, Oskar J. Sandberg, Wei Li +2
Understanding the role that exciton diffusion plays in organic solar cells is a crucial to understanding the recent rise in power conversion effciencies brought about by non-fuller…
Direct quantification of quasi-Fermi level splitting in organic semiconductor devices
Drew B. Riley, Oskar J. Sandberg, Nora M. Wilson +6
Non-radiative losses to the open-circuit voltage are a primary factor in limiting the power conversion efficiency of organic photovoltaic devices. The dominant non-radiative loss i…
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…
