Natural Dextran as an Efficient Interfacial Passivator for ZnO‐Based Electron‐Transport Layers in Inverted Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
A natural dextran is introduced as an efficient interfacial modifier for the ZnO‐based electron transport layer (ETL) in inverted organic solar cells (OSCs). This modification effectively passivates defects in the ZnO layer and reduces interfacial charge carrier recombination, enabling the achievement of high efficiency, enhanced stability, and broad ...

Self-assembled palladium nanoflowers supported on fullerene: Electrochemical catalytic performance for the reduction of 4-nitrophenol

open access: yesElectrochemistry Communications, 2019
Loading metal nanoparticles on the surface of nanosheet supports is an attractive approach to enhancing their catalytic performance. Herein, palladium nanoflowers (Pd NFs) were prepared on amino-functionalized fullerene (C60-NH2) by hydrothermal self ...

Langmuir‐Type Build‐Up of Self‐Generated Interlayers in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Metal‐induced migration of polyethylene glycol (PEG) oligomer additives to Al contacts follows a Langmuir‐like adsorption behavior forming interfacial dipole layers. Consistent Voc‐concentration trends across various additives in two distinct organic solar cell systems demonstrate the generality of the phenomenon.

Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.

Pharmacological Studies on Fullerene (C60), a Novel Carbon Allotrope, and Its Derivatives

open access: yesJournal of Pharmacological Sciences, 2006
.: Fullerene (C60), a condensed ring aromatic compound with extended π systems, is a novel carbon allotrope. Because of its poor solubility in polar solvents, investigation of the biological and pharmacological properties of fullerene has been difficult.
