Abstract Perovskite (PVK) solar cells (PSCs) have garnered considerable research interest owing to their cost-effectiveness and high efficiency. A systematic annual review of the on PSCs is essential for gaining a comprehensive understanding current trends. Herein, analysis papers reporting key findings in 2023 was conducted. Based results, were categorized into six classifications, including regular n–i–p PSCs, inverted p–i–n PVK-based tandem cells, PVK modules, device stability, lead toxicity green solvents. Subsequently, detailed overview summary advancements within each classification presented. Overall, this serves as valuable resource guiding future endeavors field PSCs.

The two-dimensional (2D) perovskites have drawn intensive attention due to their unique stability and outstanding optoelectronic properties. However, the debate surrounding spatial phase distribution band alignment among different 2D phases in quasi-2D perovskite has created complexities understanding carrier dynamics, hindering material device development. In this study, we employed highly sensitive transient absorption spectroscopy investigate dynamics of (BA)2(MA)n−1PbnI3n+1 Ruddlesden–Popper thin films, nominally prepared as n = 4. We observed carrier-density-dependent electron hole transfer between three-dimensional (3D) phases. Under a low density within linear response range, successfully resolved three ultrafast processes both transfers, spanning from hundreds femtoseconds several picoseconds, tens picoseconds nanoseconds, which can be attributed lateral-epitaxial, partial-epitaxial, disordered-interface heterostructures 3D By considering interplay structure, alignment, proposed synthesis strategies aimed at enhancing transport. Our results not only provide deep insights into an accurate intrinsic photophysics but also inspire advancements practical application these materials.

Abstract 2D Dion–Jacobson (DJ) tin halide perovskite shows impressive stability by introducing diamine organic spacer. However, due to the dielectric confinement and uncontrollable crystallization process, DJ usually exhibits large exciton binding energy poor film quality, resulting in unfavorable charge dissociation, carrier transport device performance.
