Managing Phase Orientation and Crystallinity of Printed Dion-Jacobson 2D Perovskite Layers via Controlling Crystallization Kinetics

Yijun Chen et al.

Summary: This article reports the scalable printing of high-quality Dion-Jacobson (DJ) perovskite thin films via tailoring crystallization kinetics. The perovskite films obtained through the optimized crystallization process exhibit enhanced crystallinity, highly vertical orientation, and graded phase distribution, resulting in efficient charge generation and ultrafast interphase charge transfer. The devices processed from the ternary solvent show improved stability under stimuli with light, heat, and humidity, benefiting from their superb phase stability. This work demonstrates an important advancement in scalable deposition of DJ perovskite thin films for efficient and stable photovoltaic devices.

A finely regulated quantum well structure in quasi-2D Ruddlesden-Popper perovskite solar cells with efficiency exceeding 20%

Jianghu Liang et al.

Summary: Introducing a quantum well reversely graded structure through isopropanol washing into FA-MA mixed 2D perovskite films reduces the quantum confinement effect inside the film, extends the external quantum efficiency response wavelength, and results in out-of-plane orientation, significant grain size, and long carrier lifetime. An unprecedented power conversion efficiency of 20.12% was achieved, with high stability demonstrated through aging tests under different conditions.

Crystallization in one-step solution deposition of perovskite films: Upward or downward?

Shangshang Chen et al.

Summary: Research has shown that perovskite films prepared by one-step solution processes grow downward during thermal annealing, starting from an intermediate phase rather than from bottom to top. Understanding this vertical heterogeneity of perovskite films is crucial as it significantly impacts the efficiency and stability of perovskite solar cells.

Multiple-Ring Aromatic Spacer Cation Tailored Interlayer Interaction for Efficient and Air-Stable Ruddlesden-Popper Perovskite Solar Cells

Chang Liu et al.

Summary: Novel perovskites with mixed spacers and inorganic slabs were successfully fabricated to enhance the interlayer interaction in 2DRP perovskites. Incorporating NMA cations improved the hydrogen bonding interaction between spacer cations and inorganic slabs, resulting in efficient charge carrier transport. The champion device achieved a power conversion efficiency of 14.21% and retained 85% of its initial efficiency for 1200 hours under humid conditions, demonstrating the potential for highly efficient and air-stable perovskite solar cells.
