On the unipolarity of charge transport in methanofullerene diodes

npj Flexible Electronics, 2017
Optoelectronics: Unipolar electron transport in fullerene diodes Fullerenes are commonly used in organic solar cells to attract and trap negatively charged electrons, whilst being able to block positively charged holes in photodiodes applications.

Recent progress on high-pressure and high-temperature studies of fullerenes and related materials

Matter and Radiation at Extremes, 2019
Polymerization of fullerenes is an interesting topic that has been studied for almost three decades. A rich polymeric phase diagram of C60 has been drawn under a variety of pressure P and temperature T conditions.

Hybrid Semi‐Transparent Perovskite‐Photovoltaics and Concentrated Solar‐Thermal Harvesting Collectors

Advanced Science, EarlyView.
A hybrid semi‐transparent perovskite‐photovoltaic and concentrating solar‐thermal collector is developed to spectrally split sunlight for simultaneous electricity and heat generation. The design achieves thermal decoupling between the photovoltaic and thermal components, offering a promising route for efficient co‐harvesting of solar electricity and ...

Synergistic Effects of Separator Architecture and Electrolyte Chemistry on the Electrochemical Stability of Lithium Ion Batteries With Li–Mn Rich Cathodes and µ‐Si Anodes

Advanced Science, EarlyView.
This work reveals that synergistic engineering of separator architecture and electrolyte chemistry determines the long‐term stability of LMR||µ‐Si cell chemistry. The introduction of N, N‐dimethylsulfamoyl fluoride (DMFSA) as a co‐solvent with fluoroethylene carbonate (FEC) promotes robust interphases on both electrodes, effectively mitigates side ...

Core and π‐Bridge Engineering to Deconstruct Y6‐Series into Modular Non‐Fused Acceptors: DFT‐Guided Structure‐Property Map for Organic Solar Cells

Advanced Electronic Materials, EarlyView.
The rigid fused backbone of Y6‐series acceptors is deconstructed into a modular, non‐fused A‐π‐A′‐π‐A architecture. Comprehensive quantum chemical simulations reveal that strategic core and π‐bridge engineering preserves strong near‐infrared light‐harvesting and enhances intramolecular charge‐transfer character.

Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp3 Hybridization

Angewandte Chemie, EarlyView.
A new carbon allotrope with mixed sp–sp3 hybridization has been synthesized through delicately controlled kinetics at a liquid–liquid interface. The resulting material, termed diamondiyne, exhibits an expanded diamond‐type network in the form of small crystallites in a continuous all‐carbon film.

Pairing Non‐Fullerene Acceptors With the Right Polymer: Impact of Phase Morphology and Short‐Range Transport on Charge Generation

Advanced Electronic Materials, EarlyView.
This study investigates polymer requirements for pairing with high‐efficiency non‐fullerene acceptors (NFA) in organic photovoltaics by comparing three polymer blends across varied phase morphologies. The generation of free charges is driven by fast transport‐assisted charge separation combined with slow intrinsic recombination.

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

Angewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Inorganic nanotubes and fullerenes

, 2001
The possibility of stable non-carbon fullerenes is discussed for the case of phosphorus fullerene-like cage structures. On the basis of Density Functional Tight Binding calculations it is shown that many such cages correspond to metastable structures ...

From Laboratory to Industry: Evaporating Functional Layers at High Rates for Fully Textured Perovskite/Silicon Tandems

Advanced Energy Materials, EarlyView.
Perovskite/silicon tandem solar cells exhibit outstanding efficiencies; however, the development of scalable and high‐throughput manufacturing processes remains a critical challenge. Here, we demonstrate accelerated deposition of multiple functional layers via high‐rate thermal evaporation without compromising film quality or device performance.
