“…In addition, the BF 4 anion as a pseudohalide anion effectively decreased the lattice strain and stabilized the perovskite structure. The IMBF 4 145 In comparison to UiO-66, the electrondonating amino group of UiO-66-NH 2 interacted with uncoordinated Pb 2+ /Sn 2+ to achieve efficient defect passivation and inhibit defect-related carrier recombination. The UiO-66-NH 2 -modified normal PSCs exhibited a better PCE of 13.93% than the pristine (9.94%) and UiO-66-modified (10.17%) cells.…”

“…In addition, the IMBF 4 -engineered cell exhibited a high PCE retention rate of >90% after aging in a N 2 -filled glovebox for 1000 h, which was much more superior to that of the unmodified cell under the same conditions (a PCE retention rate of 70%). Chang et al have successfully fabricated high-performance MAPb 0.75 Sn 0.25 I 3 -based PSCs by adding metal–organic frameworks, such as UiO-66 and UiO-66-NH 2 , into the perovskite precursor solution .

Low-cost perovskite solar cells (PSCs) with high power conversion efficiencies (PCEs) of >25% are considered as the most promising replacement for commercial silicon-based solar cells to realize a sustainable future. To break the theoretical PCE limits of single-junction PSCs, all-perovskite tandem solar cells consisting of a narrow-band-gap bottom subcell and a wide-band-gap top subcell have attracted particular attention recently. Mixed Pb–Sn perovskites with narrow band gaps have received great attention as an efficient light harvester in the bottom subcell of all-perovskite tandem solar cells as a result of the reduced toxicity, high light-absorbing capability, and matched current with the wide-band-gap top subcells. However, mixed Pb–Sn narrow-band-gap PSCs suffer from low PCEs, inferior stability, and high open-circuit voltage (V oc) loss, owing to the high defect amount and inferior perovskite film quality induced by the detrimental oxidation of Sn2+ cations and the rapid crystallization of perovskite crystals. Herein, the recent advances about the additive engineering for mixed Pb–Sn narrow-band-gap PSCs are reviewed by demonstrating the origins and unique features of Pb–Sn narrow-band-gap perovskites. Additionally, several strategies to improve PCEs and durability of Pb–Sn narrow-band-gap PSCs through additive engineering are proposed, including Sn2+ cation stabilization, heterojunction construction, crystallization control, surface/grain boundary passivation, film morphology control, carrier dynamics modulation, and gradient-distributed film formation. Furthermore, the existing challenges and future directions are also presented, aiming to provide important insights for designing and developing efficient and stable single-junction narrow-band-gap PSCs and all-perovskite tandem solar cells.

In modern society, photodetectors (PDs) have permeated virtually all areas of human life, from home appliances to space exploration. This versatility generates a high demand for photodetectors. It is attributed to their ability to detect signals spanning a broad spectrum of wavelengths while possessing advantageous mechanical properties such as light weight, flexibility, and low cost. Metal halide perovskites (PSKs) have recently emerged as effective photodetectors because their detection range extends from the visible spectrum to the near-infrared (NIR) spectrum through the adjustment of the chemical composition. In addition to having notable successes in photovoltaic applications, perovskites have gained attention in photodetector applications due to their superior optoelectronic properties. Incorporating toxic Pb offsets the desirability of such a high performance as the main component of perovskites. This issue was addressed by replacing Pb with relatively nontoxic Sn to retain the unique optoelectronic properties of perovskites. To promote the continued advancement of perovskites with reduced toxicity, we provide a comprehensive overview of current research on Sn and Sn−Pb mixed perovskites, emphasizing crystal structures, optoelectronic properties, synthesis, and modification methods. We then highlight exemplary applications of Sn and Sn−Pb perovskites through detailed introductions. Simultaneously, current challenges and respective solutions to the development of Sn perovskites are discussed in this Review. This Review concludes with a novel outlook on future research directions for Sn-rich perovskite photodetectors as potential candidates for enhancing light signal detection technologies. We explain how this enhancement enables performance comparable to that of commercially available crystalline Si and III−V photodetectors.
