Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells
Advanced Energy Materials, EarlyView.It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.

Randomized preclinical study of machine perfusion in vascularized composite allografts
BJS (British Journal of Surgery), EarlyView., 2020 This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

Zinc Grid Based Transparent Electrodes for Organic Photovoltaics
Advanced Energy Materials, EarlyView.A transparent flexible electrode based on an embedded zinc grid with ≈1 µm linewidth is reported, and its utility as a drop‐in replacement for indium‐tin oxide coated glass electrodes in organic photovoltaic devices is demonstrated. The zinc grids are fabricated using the unconventional approach of condensation coefficient modulation, using a ...

Advanced Energy Materials, EarlyView.A combination of morphological, electrical, and spectroscopy techniques is used to evaluate the degradation mechanisms of non‐fullerene (NFA)‐based organic photovoltaics (OPVs). Blends based on Y12 are more stable than Y6, aspeciallyOPVs from FO6‐T:Y12 demonstrated superior stability with an extrapolated T80 of over 2000 hours under maximum power point

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Advanced Energy Materials, EarlyView.Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Advanced Energy Materials, EarlyView.A unified analytical model is developed to consistently interpret the steady‐state and small‐perturbation response of photoanodes, both in the time and frequency domain. By accounting for non‐ideal electron extraction and slow hole kinetics, the model explains key experimental trends in the case of a hematite photoanode and allows extraction of related
