Capacitance of Undoped Thin-Film Diodes
Oskar J. Sandberg, Mathias Nyman, Stefan Zeiske +3
The capacitance of thin-film diodes based on undoped semiconductors are dominated by injected charge carriers rather than doping-induced carriers. However, an analytical framework…
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…
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…
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…
