When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Generating VaR Scenarios under Solvency II with Product Beta Distributions

Risks, 2018
We propose a Monte Carlo simulation method to generate stress tests by VaR scenarios under Solvency II for dependent risks on the basis of observed data. This is of particular interest for the construction of Internal Models.

Statistical Error Analysis for the Direct Simulation Monte Carlo Technique

Journal of Computational Physics, 1996
The ways of analyzing and the minimization of statistical errors of the direct simulation Monte Carlo method are studied. The dependence of the statistical error on the execution time, the particle number per cell, and the memory usage is discussed. Simulations for three kinds of flow (low Mach number supersonic flow, hypersonic flow, and expansion ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.
