Power-law density of states in organic solar cells revealed by the open-circuit voltage dependence of the ideality factor
Maria Saladina, Christopher Wöpke, Clemens Göhler +9
The density of states (DOS) is fundamentally important for understanding physical processes in organic disordered semiconductors, yet hard to determine experimentally. We evaluated…
Preconditioning for a Phase-Field Model with Application to Morphology Evolution in Organic Semiconductors
Kai Bergermann, Carsten Deibel, Roland Herzog +3
The Cahn--Hilliard equations are a versatile model for describing the evolution of complex morphologies. In this paper we present a computational pipeline for the numerical solutio…
Traps and transport resistance: the next frontier for stable state-of-the-art non-fullerene acceptor solar cells
Christopher Wöpke, Clemens Göhler, Maria Saladina +17
Stability is one of the most important challenges facing organic solar cells (OSC) on their path to commercialization. In the high-performance material system PM6:Y6 studied here,…
Spin-chemistry concepts for spintronics scientists
Konstantin L. Ivanov, Alexander Wagenpfahl, Carsten Deibel +1
Spin chemistry and spintronics developed independently and with different terminology. Until now, the interaction between the two fields has been very limited. In this review, we c…
Charge Photogeneration in Non-Fullerene Organic Solar Cells: Influence of Excess Energy and Electrostatic Interactions
Maria Saladina, Pablo Simón Marqués, Anastasia Markina +11
In organic solar cells, photogenerated singlet excitons form charge transfer (CT) complexes, which subsequently split into free charge carriers. Here, we consider the contributions…
Nongeminate and Geminate Recombination in PTB7:PCBM solar cells
A. Foertig, J. Kniepert, M. Gluecker +4
A combination of transient photovoltage (TPV), voltage dependent charge extraction (CE) and time delayed collection field (TDCF) measurements is applied to poly[[4,8-bis[(2-ethylhe…
