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

Shapes of leading tunnelling trajectories for single-electron molecular ionization

, 2011
Based on the geometrical approach to tunnelling by P.D. Hislop and I.M. Sigal [Memoir. AMS 78, No. 399 (1989)], we introduce the concept of a leading tunnelling trajectory. It is then proven that leading tunnelling trajectories for single-active-electron

Toward Reuse‐Ready PV: A Perspective on Recent Advances, Practices, and Future Challenges

Advanced Energy and Sustainability Research, EarlyView.
This perspective study sheds light on current research and future challenges toward higher PV reuse readiness in PV industry. It highlights qualification methods, PV repair strategies, and standardization efforts for PV reuse. A four‐step example of triage‐for‐reuse framework is discussed, as well as recent advances in PV repair strategies for reuse ...

Two semi-Lagrangian fast methods for Hamilton-Jacobi-Bellman equations

, 2013
In this paper we apply the Fast Iterative Method (FIM) for solving general Hamilton-Jacobi-Bellman (HJB) equations and we compare the results with an accelerated version of the Fast Sweeping Method (FSM).

An investigation of the price discovery role of futures markets: A dynamic time warping analysis of the United States corn markets

Agribusiness, EarlyView.
Abstract Futures markets are critical to price discovery and often dominate spot markets. We analyze the linkages between daily corn futures and spot prices in the United States using dynamic time warping. This nonparametric pattern recognition technique has several advantages over traditional time series methods.

An augmented Fast Marching Method for computing skeletons and centerlines

, 2002
We present a simple and robust method for computing skeletons for arbitrary planar objects and centerlines for 3D objects. We augment the Fast Marching Method (FMM) widely used in level set applications by computing the paramterized boundary location every pixel came from during the boundary evolution.
