Summary: Coating CsPbI3-xBrx perovskite with DMAII can passivate surface traps, stabilize the perovskite phase, improve hole extraction, suppress charge recombination, and significantly enhance power conversion efficiency. The DMAII coating also effectively inhibits phase transition and maintains PCE under humid or heating conditions, making it a promising material for enhancing the performance and stability of all-inorganic perovskite solar cells.

Summary: In this study, a novel approach to improve charge transport and device performance in two-dimensional RP CsPbI3 perovskite solar cells (PSC) was proposed by developing a multiple-ring aromatic spacer. The use of 1-naphthylamine (1-NA) spacer with extended pi-conjugation lengths was found to reduce the exciton binding energy and facilitate efficient separation of excitons. The cations of the spacer also made a significant contribution to the conduction band, leading to a reduced bandgap and improved interlayer charge transport. The strong pi-pi conjugation of the spacer enhanced intermolecular interactions and hydrogen bonding, resulting in high-quality films with preferred vertical orientation and lower defect density. The (1-NA)(2)(Cs)(3)Pb4I3 PSC achieved a record 16.62% performance with enhanced stability.

Summary: Triiodide cesium lead perovskite has the potential to be used in efficient and stable photovoltaics. However, the development of inverted devices and their compatibility with tandem devices is still a challenge. This study finds that the surface components of CsPbI3 are lead-poor and the traps present are p-type with localized states. This leads to poor electron transfer and nonradiative recombination, affecting the performance of the photovoltaics. Polishing treatment with 1,4-butanediamine can eliminate these traps and improve the efficiency of the CsPbI3 photovoltaics.

Summary: CsPbI3 all-inorganic perovskite has superior thermal stability compared to its organic-inorganic hybrid counterparts. However, it suffers from phase instability when exposed to moisture. By engineering the additives in the hole transport material (HTM), the phase transition of CsPbI3 can be accelerated or mitigated, leading to improved stability and performance of solar cells.

Summary: In this research, a ligand-engineered deposition strategy was proposed to improve the performance of planar perovskite solar cells. By using tartaric acid as the ligand, particle aggregation was effectively inhibited, and the interfacial contact impedance was reduced while the electron extraction was enhanced. The obtained PCE of 24.8% with a fill factor exceeding 0.83 is the highest reported among TiO2-based planar PSCs so far.

Summary: Compared to its hybrid counterparts, all-inorganic beta-CsPbI3 exhibits superior chemical and thermal stability. However, the stability of beta-CsPbI3 perovskite solar cells (PSCs) under normal operating conditions is still not as good as hybrid counterparts. A study found that lattice distortion near the perovskite/electron transport layer (ETL) interface can induce polymorphic transformation in aged CsPbI3 films. By introducing strain-release layers (SRLs) at the perovskite/ETL interface, the lattice distortion is effectively suppressed, leading to improved charge transfer and stability. Incorporating this approach in beta-CsPbI3 solar cells resulted in high efficiency and long operational lifetime under continuous illumination.

Summary: The study revealed that phenyltrimethylammonium iodide (PTAI) and its corresponding LD perovskites demonstrate excellent thermal stability. Further investigation showed that PTAI-based LD perovskites are mainly distributed at grain boundaries, enhancing the phase stability of CsPbI3 and suppressing non-radiative recombination. As a result, the champion PSC device based on CsPbI3 achieved a record efficiency of 21.0% with high stability.
