Summary: Interface passivation with metal-free H2-phthalocyanine (H2Pc) improves the efficiency and stability of perovskite solar cells (PSCs) by repairing defects and modifying energy levels. H2Pc molecules interact more effectively with unsaturated Pb and I sites compared to metal phthalocyanines. The defects passivation and improved crystallinity are achieved through coordination bonding and hydrogen bonding. H2Pc treatment also improves energy level alignment and charge extraction.

Summary: A new FMCW Lidar system is proposed to measure distance and velocity using a frequency-shifted probe light, allowing for unambiguous measurement. The system utilizes an acousto-optic modulator to induce an optical frequency shift and generates a beat signal that is up converted to avoid signal aliasing. Experimental results demonstrate real-time measurement of a spinning disk, achieving a precision of 16 mm for distance and 0.037 m/s for velocity. The system is also capable of determining the rotation direction and reconstructing a three-dimensional image of the spinning disk.

Summary: The formation of a two-dimensional (2D) perovskite layer on top of a three-dimensional (3D) perovskite has been shown to reduce charge recombination, improve performance, and enhance stability in perovskite solar cells (PSCs). However, creating a precise 2D/3D perovskite heterojunction through a solution-only process is challenging due to uncontrolled cation exchange, resulting in energy level mismatches. This study demonstrates the successful growth of a 2D perovskite with a spacer cation on a 3D perovskite film using the solid-state heat-pressure method. The introduction of 2D perovskite improves energy level alignment, enhances the hydrophobicity of the perovskite, and achieves a higher power conversion efficiency (PCE) of 15.63% compared to the control 3D device (11.88%).

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
