Summary: In this study, a novel approach to improve charge transport and device performance in two-dimensional RP CsPbI3 perovskite solar cells (PSC) was proposed by developing a multiple-ring aromatic spacer. The use of 1-naphthylamine (1-NA) spacer with extended pi-conjugation lengths was found to reduce the exciton binding energy and facilitate efficient separation of excitons. The cations of the spacer also made a significant contribution to the conduction band, leading to a reduced bandgap and improved interlayer charge transport. The strong pi-pi conjugation of the spacer enhanced intermolecular interactions and hydrogen bonding, resulting in high-quality films with preferred vertical orientation and lower defect density. The (1-NA)(2)(Cs)(3)Pb4I3 PSC achieved a record 16.62% performance with enhanced stability.

Summary: In this study, a novel ternary TiO2/CdS/TiN nanorod array (NRA) photoanode is demonstrated for high-efficiency photoelectrochemical H2 generation. The photoanode is constructed by modifying TiO2 nanorod arrays with two-dimensional (2D) CdS nanosheets and nonmetal plasmonic TiN nanoparticles. The enhanced H2 generation of the TiO2/CdS/TiN NRA photoanode is attributed to effective hot-electron injection and charge separation, achieved through the improved visible light absorption, extended contact area, and enhanced photon energy utilization provided by the 2D CdS nanosheets and TiN nanoparticles.

Summary: Perovskites, as one of the most promising candidates for X-rays imaging materials, have received extensive attention. However, poor stability and undesirable ion migration hinder their development. In recent years, two-dimensional (2D) perovskite materials have been successfully developed to address these issues, but the preparation of pure phase single crystals remains challenging. This study demonstrates the use of a 2D perovskite single crystal, BA(2)PbBr(4), as a representative model, grown using a simple solution temperature lowering (STL) synthesis method. The crystal exhibits a short fluorescence lifetime, intense X-rays radioluminescence, and high environmental and temperature stability. It has also been used in X-rays imaging, showing good imaging results and stability. This research highlights the great potential of 2D perovskites in low-cost X-rays imaging systems.
