Unveiling Energy Loss Mechanisms to Empower Ternary Organic Solar Cells with over 20% Efficiency: A Systematic Oligomeric Approach

open access: yesAdvanced Materials, EarlyView.
This study designs modular oligomeric donors (5BDD, 5BDD‐F, 5BDT‐F, 5BDT‐Cl) for ternary OSCs, achieving PCEs >20%. By systematically tuning energy levels, we reveal material compatibility, not HOMO alignment, drive VOC enhancement, suppress ACQ and reduce energy loss, offering new design principles for high‐efficiency OSCs.

Mitigating Mobile‐Ion‐Induced Instabilities and Performance Losses in 2D Passivated Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
This study addresses the challenges of mobile‐ion‐induced instability in perovskite solar cells. Introducing bilayer passivation with ammonium salts (EDAI₂/PEAI and ABS/PEAI) significantly reduces ion density and improves device stability. The approach mitigates the detrimental effects of PEAI‐induced ionic losses, enhancing both performance and ...

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

open access: yesAdvanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent
