Unraveling the Roles of Shallow, Deep and Auger Trapping in Charge Carrier Recombination in Triple-Cation Perovskites
Jitendra Kumar, Thomas Kirchartz, Alexandr Marunchenko +7
Understanding charge-carrier recombination in metal halide perovskites is essential for accurately identifying the factors limiting solar cell efficiency, yet it remains challengin…
Rethinking Charge Transport and Recombination in Donor-diluted Organic Solar Cells
Chen Wang, Christopher Wöpke, Toni Seiler +12
We systematically investigate PM6:Y12 bulk-heterojunction solar cells with donor fractions ranging from 1% to 45%, linking morphology, charge transport, and recombination to device…
Wide-angle emission in cylindrical moiré lattices enabled by rolling origami
Min Tang, Fanzhou Lv, Haiyun Dong +8
Twisted photonic lattices that form moiré superlattices have attracted significant attention owing to their unique properties, such as strong field confinement and high-quality fac…
Molecular Cross-linking of MXenes: Tunable Interfaces and Chemiresistive Sensing
Yudhajit Bhattacharjee, Lukas Mielke, Mahmoud Al-Hussein +10
MXenes, a family of 2D transition metal compounds, have emerged as promising materials due to their unique electronic properties and tunable surface chemistry. However, the transla…
Exciton diffusion in two-dimensional chiral perovskites
Sophia Terres, Lucas Scalon, Julius Brunner +10
Two-dimensional (2D) organic-inorganic hybrid perovskites emerged as a versatile platform for light-emitting and photovol-taic applications due to their unique structural design an…
Hidden photoexcitations probed by multi-pulse photoluminescence
Alexandr Marunchenko, Jitendra Kumar, Dmitry Tatarinov +3
Time-resolved photoluminescence is a validated method for tracking the photoexcited carrier dynamics in luminescent materials. This technique probes the photoluminescence decays up…
