Summary: High-quality lead sulfide films were successfully fabricated by H2S-free metal-organic chemical vapor deposition (MOCVD) using a single-source metal-organic complex. The films exhibited chemically stoichiometric and homogenous properties, with high crystallinity and comparable charge transport characteristics as those produced by atomic layer deposition (ALD). Photodetectors fabricated with these films showed high photocurrents, reliable switching characteristics, and high sensitivity over a broad spectral bandwidth, indicating their potential for practical broadband photodetection.

Summary: Vapor deposition shows great potential for scalable and industrial processing of perovskite solar cells, offering advantages such as toxicity-free processing, thickness control, and uniform coating. However, the different volatilities of the organic and inorganic components of perovskites currently require multiple thermal sources or two-step deposition. In this study, single-source, single-step pulsed laser deposition is demonstrated for the deposition of tunable MA(1-x)FA(x)PbI(3) thin films. The room temperature formation of cubic alpha-phase MA(1-x)FA(x)PbI(3) films is achieved by controlling laser ablation of a solid target with adjustable ratios of MAI:FAI:PbI2. The target-to-film transfer of the ablated species is confirmed, and proof-of-concept solar cells with 14% efficiency are demonstrated. This research paves the way for future developments in industry-compatible vapor deposition methods for perovskite solar cells.

Summary: In recent years, the efficiency of perovskite solar cells has increased, but the commercialization of large-scale production of perovskite thin films still faces challenges due to the formation of pinholes. Current techniques are not advanced enough to produce pinhole-free perovskite thin films on a large scale. This study introduces a valine treatment process for obtaining compact and pinhole-free perovskite thin films, which significantly improves the efficiency of perovskite solar cells.

Summary: In this study, CsSnBr3 films with controlled grain boundaries and surfaces were successfully prepared using a solid-source chemical vapor deposition method. The increase in grain size of CsSnBr3 films results in reduced grain boundaries. Photodetectors based on CsSnBr3 films with decreased grain boundaries exhibit excellent performance and fast response times.

Summary: Hybrid lead-halide perovskite materials have impressive optoelectronic properties, but the toxic nature of lead and instability issues have led researchers to explore low-toxic substitutes like antimony and bismuth ternary halide perovskites. These new materials are considered promising for next-generation photovoltaic technology due to their stability and high absorption coefficient. However, they still face challenges such as large bandgaps and dimer phases, requiring further research and improvement.
