Summary: The passivation of surface defects of perovskites using organic functional materials has been demonstrated to enhance the efficiency and stability of solar cells. Two solution-processable 2D conjugated polymers, 2DP-F and 2DP-O, were synthesized and found to successfully passivate defects and improve charge carrier extraction in perovskite solar cells.

Summary: The interface properties of organic-inorganic mixed halide perovskite solar cells are crucial for their photovoltaic performance. Researchers have successfully constructed a robust interface for perovskite films through mixed-dimensional engineering, reducing the number of defect states and increasing the lifetime of photocarriers. The introduction of a one-dimensional capping layer also acts as a diffusion barrier and protects the vulnerable perovskite against moisture. Perovskite solar cells based on stacked one-dimensional/three-dimensional structures exhibit high efficiency and stability, surpassing the performance of three-dimensional devices.

Summary: In this study, interlayer molecules with different side groups were designed to investigate the correlation between defect-passivation strength and interfacial carrier dynamics in polycrystalline perovskite. It was found that the introduction of Cl-grafted molecules or cyanide (CN) as a side group led to destructive effects and deformation of the perovskite structure. However, the incorporation of carbonyl (C=O) as the side group (TPA-O) effectively promoted carrier-collection yield and defect passivation, resulting in high efficiency and stability in perovskite solar cells. This work provides a potential strategy for improving the performance of perovskite solar cells.

Summary: By using ligand-biphenyl-3,3',5,5'-tetracarboxylic acid butyl amine (BPTC-BN) to passivate defects at the SnO2/perovskite interface, the size and quality of perovskite grains could be improved, leading to enhanced performance of planar PSCs. This interface passivation strategy not only increases the efficiency and open voltage of the devices, but also substantially improves their operational stability.

Summary: This study explores the impact of bulky-cation-modified interfaces on the stability of halide perovskite solar cells. The results demonstrate the thermal instability of the bulky-cation interface layers used in state-of-the-art solar cells, which significantly affects the performance and operation of the devices. The type of cation used for surface treatment also influences the extent of these changes, with long carbon chains providing more stable interfaces.

Summary: In this study, the stable operation of Li-0-SPAN batteries was achieved through a dual-passivation approach using a fluorinated localized high concentration electrolyte and a Li3N-forming additive. The resulting highly reversible, dendrite-free, and high-density Li-0 plating morphology, along with the eliminated Li2S formation and minimized polysulfide dissolution, provides valuable insights for the rational design of highly durable and high-energy-density Li-0-S batteries.

Summary: This study systematically investigated the structural compatibility between commercially layered cathode material NCM523 and solid-state electrolyte LATP. It was found that a severe side reaction occurs during the cosintering process, leading to a loss of capacity in the cathode material. Thus, interface modification of the NCM523/LATP interface is suggested to inhibit this side reaction and accelerate the application of LATP-based all-solid-state batteries.
