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…
Energetics and Kinetics Requirements for Organic Solar Cells to 2 Break the 20% Power Conversion Efficiency Barrier
Oskar J Sandberg, Ardalan Armin
The thermodynamic limit for the efficiency of solar cells is predominantly defined by the energy bandgap of the used semiconductor. In case of organic solar cells both energetics a…
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…
