Over 21% Efficiency Stable 2D Perovskite Solar Cells

Ming Shao et al.

Summary: This study fabricated 2D perovskite solar cells incorporating FA, MA, and FA/MA, resulting in significantly enhanced light absorption and device stability. The introduction of FA cations increased the 3D-like phase relative to 2D phases and effectively suppressed the formation of the yellow delta phase.

Size-Dependent Hot Carrier Dynamics in Perovskite Nanocrystals Revealed by Two-Dimensional Electronic Spectroscopy

Buyang Yu et al.

Summary: The study demonstrates the presence of a phonon bottleneck effect in CsPbI3 nanocrystals through broadband two-dimensional electronic spectroscopy, showing a size-dependent relaxation of hot carriers and doubling of their lifetime as the nanocrystal size decreases. This finding suggests the feasibility of controlling hot carrier dynamics in perovskite semiconductors for potential applications.

Spin blockade and phonon bottleneck for hot electron relaxation observed in n-doped colloidal quantum dots

Junhui Wang et al.

Summary: Understanding and manipulating hot electron dynamics in semiconductors could lead to innovative energy conversion technologies. By studying electron-doped CdSe quantum dots, the researchers observed different relaxation mechanisms of hot electrons at various doping levels and were able to prolong the hot electron lifetime up to 320 picoseconds, offering new opportunities for hot electron harvesting in doped quantum dots.

Ultrafast and High-Yield Polaronic Exciton Dissociation in Two-Dimensional Perovskites

Qi Sun et al.

Summary: Contrary to theoretical predictions, ultrafast and highly efficient internal exciton dissociation was discovered in 2D lead halide perovskites, attributed to exciton-polarons formation and reduced exciton binding energy by polaronic screening. This unique property limits photoluminescence but explains exceptional performance in photovoltaic devices, offering insights for rational applications in light emitting and photovoltaics within the 2D hybrid perovskite family.

Strong Triplet-Exciton-LO-Phonon Coupling in Two-Dimensional Layered Organic-Inorganic Hybrid Perovskite Single Crystal Microflakes

Yunuan Wang et al.

Summary: This study reports a strong coupling between triplet excitons and longitudinal-optical phonons in 2D layered hybrid perovskites, with the coupling strength significantly higher than that of singlet excitons. This understanding of the triplet exciton-LO phonon coupling provides insight into many-body interactions in hybrid perovskites, which can be beneficial for the development and optimization of optoelectronic devices based on 2D perovskites in the future.

Enhancing the Hot-Phonon Bottleneck Effect in a Metal Halide Perovskite by Terahertz Phonon Excitation

Fumiya Sekiguchi et al.

Summary: The impact of phonon excitations on the photoexcited carrier dynamics in lead-halide perovskite CH3NH3PbI3 was investigated, showing that strong terahertz excitation can prolong the cooling time of hot carriers. The results demonstrate that phonon excitation significantly perturbs the carrier relaxation dynamics in halide perovskites through the coupling between transverse- and longitudinal-optical phonons.

Auger-Assisted Electron Transfer between Adjacent Quantum Wells in Two-Dimensional Layered Perovskites

Zixi Yin et al.

Summary: Two-dimensional layered perovskites hold great promise for optoelectronic applications, but are limited in some devices by the lack of carrier transport between quantum wells. This study reports an Auger-assisted electron transfer mechanism between adjacent quantum wells in 2D perovskites, providing a new guideline for designing perovskites with optically tunable charge transport properties.

Manganese doping for enhanced magnetic brightening and circular polarization control of dark excitons in paramagnetic layered hybrid metal-halide perovskites

Timo Neumann et al.

Summary: The study explores the magneto-optical properties of Mn-doped Ruddlesden-Popper hybrid perovskites, revealing magnetically brightened excitonic luminescence with strong circular polarization and the brightening of dark exciton population by state mixing with bright excitons in the presence of a magnetic field. Unexpectedly, the circular polarization of dark exciton luminescence follows the Brillouin-shaped magnetization, indicating spin-dependent exciton dynamics at early times after excitation and a potential Mn-mediated spin-flip process.
