Query: Experimentally Calibrated Kinetic Monte Carlo Model Reproduces Organic
  Solar Cell Current-Voltage Curve   Kinetic Monte Carlo (KMC) simulations are a powerful tool to study the
dynamics of charge carriers in organic photovoltaics. However, the key
characteristic of any photovoltaic device, its current-voltage ($J$-$V$) curve
under solar illumination, has proven challenging to simulate using KMC. The
main challenges arise from the presence of injecting contacts and the
importance of charge recombination when the internal electric field is low,
i.e., close to open-circuit conditions. In this work, an experimentally
calibrated KMC model is presented that can fully predict the $J$-$V$ curve of a
disordered organic solar cell. It is shown that it is crucial to make
experimentally justified assumptions on the injection barriers, the blend
morphology, and the kinetics of the charge transfer state involved in geminate
and nongeminate recombination. All of these properties are independently
calibrated using charge extraction, electron microscopy, and transient
absorption measurements, respectively. Clear evidence is provided that the
conclusions drawn from microscopic and transient KMC modeling are indeed
relevant for real operating organic solar cell devices.
