Decoding the Structure of Benzodithiophene Polymers for High‐Efficiency Organic Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
This study reveals a unique solid mesophase in top‐performing benzodithiophene‐based polymers for solar cells, comprising stacked solid‐like and liquid‐like layers. Combining nanoscale fibrillar domains with amorphous regions, it introduces a new structural paradigm.

Some Trends in Quantum Thermodynamics

open access: yesEntropy, 2014
Traditional answers to what the 2nd Law is are well known. Some are based on the microstate of a system wandering rapidly through all accessible phase space, while others are based on the idea of a system occupying an initial multitude of states due to ...

Reversible Phase Transitions Enable Cyclic Isothermal CO2 Capture in Redox‐Activated Perovskite‐Structured Sorbents

open access: yesAdvanced Functional Materials, EarlyView.
Perovskite‐structured SrMnO3 can cyclically and reversibly capture and release CO2 via redox‐enabled phase transitions at constant temperature. The efficacy of this novel redox‐activated CO2 sorbent is demonstrated via sorption‐enhanced steam methane reforming.

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.
