Summary: The newly synthesized 2D lead halide perovskite (C9H14ON)2PbI4 exhibits strong green emission and relatively low modulus and anisotropy compared with other 2D materials. The green emission red-shifts with increasing temperature, primarily due to the synergistic effect of thermal expansion and electron-phonon interactions.

Summary: In this study, we investigated the structural and electronic properties of different types of 2D/3D perovskite heterojunctions using first-principles calculations. The RP-PbI and ACI-FAI heterojunctions showed favorable carrier transport and separation, with relatively fewer recombination losses, indicating greater potential for photovoltaic applications. Based on the direction of carrier transport at the heterojunction, we predict that RP-PbI would outperform DJ-FAI in conventional 2D/3D devices, while the ACI-FAI heterojunction is expected to function well in inverted 2D/3D devices.

Summary: Perovskite solar cells with high efficiency are seen as a promising solution for renewable energy, but the presence of toxic lead and its stability in the environment have raised concerns. This study focuses on using a lead-free material as the active layer in perovskite solar cells and doping the carrier transporting layers to improve efficiency. The devices showed good stability and maintained their high efficiency even after prolonged exposure to ambient conditions. These findings suggest that the lead-free perovskite material has potential for large-scale production.

Summary: The distributions of threading dislocations (TDs) and horizontal dislocations (HDs) in c-plane GaN epitaxial layers on a 6-inch Si wafer were determined using second harmonic generation (SHG) intensity, Raman scattering stress, photoluminescence, and reflected interference pattern. Raman scattering spectra revealed that TDs caused tensile stress in the GaN epitaxial layers while HDs caused compressive stress. Additionally, SHG intensity was found to be proportional to the stress value of the GaN epitaxial layers, providing insights into its spatial distribution. Notably, the dislocation-mediated SHG intensity mapping image of the GaN epitaxial layers on the 6-inch Si wafer could be obtained within 2 hours, making it useful for optimizing high-performance GaN-based HEMTs.

Summary: By tuning the band gaps of their active layer materials, organic photodetectors (OPDs) can display good responses in the near-infrared (NIR) region, making them useful for applications in biomedical imaging and optical communication. In this study, we used 3TT-FIC, a non-fullerene acceptor (NFA), to develop OPDs capable of operating with extremely low dark currents and high response speeds. By fine tuning the blend ratio of the donor (PM6) and acceptor (3TT-FIC), we obtained an OPD that operated at a low dark current (7.04 x 10-10 A/ cm2) at -1 V with a high value of specific detectivity (D*) (2.6 x 1013 Jones) at the wavelength of 850 nm. We also discuss the wider applicability of 3TT-FIC and its potential as an NFA in NIR OPDs.

Summary: Plasmonics has attracted attention for its ability to control light flow in metamaterials. The use of active plasmonic materials allows for the mass production of low-cost, high-performance nanosized optical components for imaging, sensing, and communications. By integrating non-volatile active materials with distinct qualities, dynamic plasmonic systems can be reconfigured to provide sharper optical variations and faster phase shifting. This review focuses on metamaterial plasmonic sensors that detect changes in refractive indices, and the use of active materials to enhance sensing and light absorption.

Summary: This study synthesized three D-7C-D type PAHs-based hole-transporting materials (HTMs) and demonstrated their efficiency in perovskite solar cells (PSCs). The PSC devices fabricated with one of the compounds, DC-1, achieved a highly efficient power conversion efficiency (PCE) of 18.09%, outperforming the devices based on DC-2 and DC-3, and slightly higher than those using the control material spiro-OMeTAD. These novel D-7C-D molecules show promising performance as HTMs for PSCs and contribute to the development of high-efficiency perovskite solar cells.

Summary: We report on the formation of a bendable and edge-on poly[3-(4-carboxybutyl)thiophene-2,5-diyl] (P3CT) polymer thin layer used as a hole modification layer (HML) in inverted perovskite solar cells. The aggregations of 2D layer-like P3CT polymers in DMF solution can be formed through aromatic π-π stacking interactions and/or hydrogen-bonding interactions. These highly influence the photovoltaic performance of the inverted perovskite solar cells. The P3CT polymers modify the surface properties of the transparent conductive substrate, dominate the formation of perovskite crystalline thin films, and play important roles in the efficient and stable perovskite solar cells.

Summary: Cesium halides, such as CsCl, CsBr, and CsI, were introduced as a modulator in the precursor of perovskite films to manipulate their crystallization. The addition of CsI resulted in dense homogeneous perovskite films with high crystallinity, preferential orientation, and a pure black perovskite phase. The carrier lifetime of the perovskite films was significantly increased, leading to an improvement in the power conversion efficiency (PCE) of the small-area devices from 17.45% to 20.29%. The devices also exhibited excellent stability, maintaining 75% of the initial PCE after 350 hours of continuous irradiation. This study demonstrates the reliable application of CsI regulation for preparing high-performance perovskite solar cells.

Summary: Manipulating the grain sizes of soft CH3NH3PbI3 (MAPbI(3)) thin films and the atomic contact strength at the MAPbI(3)/P3CT-Na interface through variations in drying time of precursor solutions has significant effects on the performance and lifespan of inverted perovskite photovoltaic cells. The increased short-circuit current density (J(SC)) and fill factor (FF) can be attributed to the formation of merged MAPbI(3) grains. Additionally, the encapsulated photovoltaic cells exhibit higher open-circuit voltage (V-OC) and power conversion efficiency due to the increased carrier density of the MAPbI(3) crystalline thin film.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
