Summary: Aluminium doped zinc oxide (AZO) shows promise as an electron transport layer (ETL) in low-temperature solution processes for hybrid perovskite solar cells (PvSCs) as a replacement for TiO2. By using a thin interfacial modification layer of monoethanolamine (MEA), the energy barrier between AZO/perovskite is reduced, accelerating charge transfer and passivating trap states. The champion PvSCs achieved an improved power conversion efficiency (PCE) of 8.25%, with a current density (J(SC)) of 22.59 mA/cm(2) and fill factor (FF) of 46.55%, and maintained 70% of its topmost PCE after 1000 hours without encapsulation. This MEA-based interface engineering offers a feasible and excellent strategy to enhance the efficiency and stability of planar PvSCs.

Summary: Inverted perovskite solar cells have gained increasing research interest, but the hydrophobic property of the commonly used hole-transporting layer material PTAA hinders the growth of high-quality perovskite films. This study employs a donor-acceptor-donor type organic molecule M2 to modify the surface of PTAA, improving its hydrophobic property and enhancing hole mobility and conductivity. With the modified PTAA/M2 as the hole transport layer, the efficiency and stability of inverted PSCs are improved.

Summary: A transformation strategy mediated by an inorganic ligand (NOBF4) was developed to obtain blue-emitting CsPbBr3 nanoplates (NPLs). The transformation process involved the dissolution and recrystallization of Cs4PbBr6 nanocrystals in a nonpolar environment, resulting in the formation of pure blue-emitting NPLs with a line width of about 12 nm. The reorganization of organic ligands tuned by NO+ played a crucial role in the formation of NPLs. This work provides an effective strategy for obtaining pure blue-emitting NPLs and offers a platform for exploring the mechanism of anisotropic growth in perovskite crystals.

Summary: Metal electrode materials are crucial for the performance of microscale perovskite-based devices. However, it is challenging to investigate the influence of different metal electrode materials on the same microscale perovskite piece. A strategy using liquid metal as top electrode was proposed to fabricate soft-sandwiched perovskite junctions, allowing for replacement of bottom electrode without damage. The shape of photocurrent is mainly controlled by light intensity, while the rectification ratio is determined by electrode materials.

Summary: In order to fabricate high-efficiency and stable nickel oxide (NiOX)-based perovskite solar cells, adverse reactions and lattice mismatch need to be overcome. Interface engineering using multi-layer passivation NiOX HTLs (NiOX/2PACz/Poly-TPD/PEAI) was carried out to optimize the interface contact, improve band alignment, and saturate defect states. Compared to single-function passivation materials, the proposed multilayer passivation integrates multiple functions. The resulting NiOX/2PACz/Poly-TPD/PEAI-based PSCs achieved a champion power conversion efficiency (PCE) of 20.21% and maintained over 95% of their initial PCE values after prolonged storage.

Summary: Passivating the defective surface of perovskite film using 1-adamantanamine hydrochloride (ATH) improves the stability and efficiency of perovskite solar cells (PSCs). The ATH-modified device shows a higher efficiency (23.45%) compared to the control device (21.53%). The defects are repaired, nonradiative recombination is suppressed, and interface stress is relieved by depositing ATH on the perovskite film, resulting in longer carrier lifetimes and enhanced VOC and FF of the PSCs. VOC and FF are increased from 1.159 V and 0.796 for the control device to 1.178 V and 0.826 for the ATH-modified device, respectively. During a stability measurement of over 1000 hours, the ATH-treated PSC exhibits improved moisture resistance, thermal persistence, and light stability.
