Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Modulating Polaron Behavior in PM6 Blends with Nonfullerene and Fullerene Acceptors: The Importance of Singlet Energy Transfer

open access: yesAdvanced Materials Interfaces, EarlyView.
Transient absorption spectroscopy is employed to demonstrate that nonfullerene acceptors inhibit the formation of bound polaron pairs in conjugated polymers, which would otherwise undergo rapid relaxation back to the ground state. Instead, efficient energy transfer from the polymer to the non‐fullerene acceptor takes place, facilitating high charge ...

AFM‐Based Functional Tomography – To Mill or Not to Mill, that is the Question!

open access: yesAdvanced Materials Interfaces, EarlyView.
Complex networks of conducting domain wall interfaces exist hidden underneath the surface of ferroelectric hexagonal manganites. It reveals the morphology and conductive properties directly by 3D tomographic atomic force microscopy. It correlates the measured surface level conductance with subsurface domain wall structure, and discuss the existence ...
