Summary: Ruddlesden-Popper (RP) tin-based halide perovskites have attracted attention due to their low-toxicity and low-cost processability. This study proposes a method to slow down crystallization kinetics in RP tin-based perovskites by regulating intra- and intermolecular interactions. By introducing an electron-rich heterocyclic thiophene into bulky spacers, the intermolecular interaction is decreased and intramolecular interactions are increased, leading to the stabilization of colloids and orderly crystal growth. The perovskite solar cell using this method demonstrates a two-fold improvement in power conversion efficiency compared to the control sample.

Summary: This study demonstrates that using bulky alkylammonium spacer cations in 2D perovskites helps in preparing high-quality phase-pure alpha-FAPbI(3) perovskite films, which leads to improved efficiency and stability of perovskite solar cells. The deprotonation process of the spacer cations during annealing removes the in situ generated 2D perovskites from the film, ultimately affecting the performance and stability of the solar cells.

Summary: The main challenges in synthesizing colloidal 2D RP organo-lead iodide perovskite nanocrystals (NCs) are phase instability and low photo-luminescence quantum yield (PLQY). By alloying with guanidinium and formamidinium cations, the optical properties and phase stability of L-2[APbI(3)]PbI4 NCs can be effectively tuned. Additionally, the band gap of the NCs can be rapidly engineered by bromide ion exchange in L-2[GA(x)FA(1-x)PbI(3)]P- I4 (0 = x = 1) NCs, producing stable dispersions with higher PLQY than previously reported.

Summary: In this study, nonhalide lead source of lead acetate is investigated for high-quality 2D Ruddlesden-Popper perovskite (RPP) films by a dimethyl sulfoxide (DMSO)-assisted delayed annealing process. The addition of DMSO in the lead acetate-based precursor solution regulates the crystallization process, resulting in RPP films with enhanced crystallinity, reduced trap density, vertical crystal orientation, and graded phase distribution. The optimized RPP solar cell with an inverted planar structure achieves a champion power conversion efficiency of 17.3%. Future developments of nonhalide lead sources are expected to further improve the performance of RPP films.

The addition of guanidinium (GA(+)) spacer enhances the optical and electrical performance of perovskite films by providing more nucleation sites and reducing the crystallization rate. The strategy also promotes the formation of polydisperse domain distribution and interaction with perovskite defects through coordination bonding. The resulting perovskite LEDs exhibit high efficiency and brightness.

Summary: This study proposes an effective lattice-matching chelation strategy to modulate the strain of perovskite films, leading to improved efficiency and stability of perovskite solar cells. The organic salt of bidentate imidazole is able to anchor the perovskite lattice, resulting in compressive-strained perovskite films and achieving better energy alignment, improved charge carrier transport, decreased nonradiative recombination, and lower trap state density. The perovskite solar cell based on this method exhibits an efficiency of 24.61% and improved long-term thermal stability, while a large-area integrated module achieves an efficiency of 20.53%.

Summary: Hybrid halide perovskite solar cells (PSCs), as the next-generation photovoltaic technology, are easily processable but prone to defects/traps during thin-film fabrication. Large-sized organic cations (LSOCs) have been used to passivate these defects, but they also lead to the formation of poorer optoelectronic layered perovskite phases. In this study, a LSOC salt called CzEAI was designed to penetrate the entire perovskite film and convert into a divalent state at defect sites, achieving full-scale passivation and improving the performance and stability of the PSCs.
