The Role of Fluorine‐Functionalized Organic Spacers for Defect Passivation and Low‐Dimensional Phase Formation in 3D MAPI Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Fluorine‐functionalized organic spacers (2F, 3F, 5F) are investigated to identify as optimal passivation agents for 3D MAPI perovskite solar cells (PSCs). The study highlights how altering fluorine positioning affects defect passivation, low‐dimensional phase (LDP) formation, and stability, emphasizing its role in molecular interactions and offering ...

Over 18% Efficiency from Halogen‐Free Solvent‐Processed Polymer Solar Cells Enabled by Asymmetric Small Molecule Acceptors with Fluoro‐Thienyl Extended Terminal

open access: yesAdvanced Functional Materials, EarlyView.
An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.

Enhancing UV Stability and Charge Extraction in Organic Solar Cells with Phenyl‐Linked Aromatic Self‐Assembled Monolayer

open access: yesAdvanced Functional Materials, EarlyView.
The phenyl‐linked self‐assembled monolayer exhibits robust intrinsic stability and hole extraction capability compared to the alkyl‐linked counterparts, thus facilitating the device stability with T80 over 1000 h and efficiency of 19.7% in advancing organic solar cells.

Dynamics of the Upper Atmosphere

open access: yesEos, Transactions American Geophysical Union, 1982
The earth's upper atmosphere is highly dynamic, receiving strong energy inputs both from below in the form of upward propagating waves and from above in the form of electromagnetic and particle radiation from the sun and magnetosphere. Above 100 km the dynamics become increasingly influenced by factors that are of minor importance in the lower ...
