Achieving 19% Power Conversion Efficiency in Planar‐Mixed Heterojunction Organic Solar Cells Using a Pseudosymmetric Electron Acceptor

Advances in Materials, 2022
A record power conversion efficiency (PCE) of over 19% is realized in planar‐mixed heterojunction (PMHJ) organic solar cells (OSCs) by adopting the asymmetric selenium substitution strategy in making a pseudosymmetric electron acceptor, BS3TSe‐4F.

An Electron Acceptor Analogue for Lowering Trap Density in Organic Solar Cells

Advances in Materials, 2021
Typical organic semiconductor materials exhibit a high trap density of states, ranging from 1016 to 1018 cm−3, which is one of the important factors in limiting the improvement of power conversion efficiencies (PCEs) of organic solar cells (OSCs).

Electron in a cube: Synthesis and characterization of perfluorocubane as an electron acceptor

Science, 2022
Fluorinated analogs of polyhedral hydrocarbons have been predicted to localize an electron within their cages upon reduction. Here, we report the synthesis and characterization of perfluorocubane, a stable polyhedral fluorocarbon.

The Design of Fused Amine/Carbonyl System for Efficient Thermally Activated Delayed Fluorescence: Novel Multiple Resonance Core and Electron Acceptor

Advanced Optical Materials, 2019
Multiple resonances induced thermally activated delayed fluorescence (MR‐TADF) has great advantages in high color purity display. Up to now, current MR‐TADF emitters are only based on the boron‐nitrogen‐containing fragment.

Cyclo[18]carbon: the smallest all-carbon electron acceptor.

Chemical Communications, 2019
The recently synthesized C18 molecule demonstrates strong electron acceptor properties similar to C60. In this work, we study computationally the ground and excited state properties of C18 and its complexes with several electron-donating molecules.

Electron donor-acceptor properties of haematoporphyrin

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1968
Abstract 1. The interaction of haematoporphyrin with a wide range of electron donors has been studied spectrophotometrically in phosphate buffer solution at pH 9 where the spectrum is insensitive to small changes of pH. 2. It has been shown that haematoporphyrin forms 1:1 complexes, the difference spectra being temperature reversible and containing ...
