The Role of Thermally Activated Charge Separation in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Charge separation mechanism in state‐of‐the‐art system has been a part of intense debate. Here, it is presented that as, the system moves toward the low‐offset regime the thermal contribution plays an important role to derive the charge separation. The rational guide is provided to achieve the maximum CSE and maximum VOC simultaneously within the mid ...

The Origin of Improved Performance in Boron‐Alloyed Silicon Nanoparticle‐Based Anodes for Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon‐boron alloy nanoparticles are incorporated into lithium‐ion batteries as the active anode material and enhance the battery cycle and calendar lifetime with improved interfacial chemical passivation. This passivation is afforded by the strong surface dipoles imparted on the particles from Lewis acidic surface boron.

In‐Scribe Silane Bonding for Mechanical Reinforcement of Perovskite Photovoltaic Modules

open access: yesAdvanced Energy Materials, EarlyView.
Research on improving the mechanical reliability of metal halide perovskite photovoltaics has overwhelmingly focused on improving the interfacial toughness of individual layers or interfaces within the cell stack. In this work, a module‐level approach is taken to address this challenge by focusing on improving strength within the dead area of the ...

Relative cost of ginning cotton using saw, conventional roller, and high‐speed roller gins in the United States

open access: yesAgribusiness, EarlyView.
Abstract The primary objective of this study was to investigate whether the cost of processing cotton using high‐speed roller gins is comparable to saw gins. The results from a “true” random effect model estimated using proprietary data voluntarily shared by cotton gins operating in Arizona and California showed that the average cost inefficiency for ...

Food Tastes in the United States: Convergence or Divergence?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.
