Photo-Effect on Ion Transport in Mixed Cation and Halide Perovskites and Implications for Photo-Demixing**

Gee Yeong Kim et al.

Summary: Lead halide perovskites are considered the most promising photovoltaic materials, with the highest efficiency and improved stability achieved through the use of cation and anion mixtures. Experimental information is crucial for evaluating device performance, and processes of photo-decomposition and photo-demixing play a role in these materials. The study found that light not only enhances electronic but also ionic conductivities, with the phenomenon being sensitive to the nature of the halide.

Spectral Instability of Layered Mixed Halide Perovskites Results from Anion Phase Redistribution and Selective Hole Injection

Yoonseo Nah et al.

Summary: This study investigates the origin of electroluminescence peak shifts in mixed halide perovskites, finding that the applied electric field drives systematic halide migration, leading to the redistribution of anions due to different activation energies required for directional ion hopping. The spectral shifting rate of electroluminescence is dependent on the drift velocity of halides, and red emission is suggested to be attributed to thermodynamically favorable selective hole injection. Insights from this mechanistic study provide understanding of the fundamental reason for the spectral instability in devices based on mixed halide perovskites.

Incorporating Electrochemical Halide Oxidation into Drift-Diffusion Models to Explain Performance Losses in Perovskite Solar Cells under Prolonged Reverse Bias

Luca Bertoluzzi et al.

Summary: Studies have shown that metal halide perovskite solar cells exhibit interesting behavior in reverse bias, including reversible performance loss and non-reversible degradation. An advanced drift-diffusion approach incorporating an electrochemical term is used to explain the losses in short-circuit, open circuit, and fill factor measured experimentally after prolonged reverse bias.

Electronic Structure and Optical Properties of Mixed Iodine/Bromine Lead Perovskites. To Mix or Not to Mix?

Valentin Diez-Cabanes et al.

Summary: Halide mixing plays a key role in tuning the emission wavelength and improving the performance of lead halide perovskites solar cells. Research shows that halide impurities do not act as trap states in low doping regime, and the bandgap opens quasi-linearly with increasing bromine content. Phase segregation at the nanoscale significantly affects the electronic structure of mixed halide systems.

Organic Hole Transport Material Ionization Potential Dictates Diffusion Kinetics of Iodine Species in Halide Perovskite Devices

Ross A. Kerner et al.

Summary: Iodine-containing volatiles are major degradation products of halide perovskite materials under irradiation. The study examines the diffusion kinetics of iodine into organic hole transport materials (HTMs) and reactions, finding a correlation between I-2 permeability and HTM ionization energy. This suggests that HTM energetics influence the stability of halide perovskite devices by suppressing iodine migration.

Reversible Pb2+/Pb0 and I-/I3- Redox Chemistry Drives the Light-Induced Phase Segregation in All-Inorganic Mixed Halide Perovskites

Lyubov A. Frolova et al.

Summary: Research shows that tunability of optoelectronic properties of lead halide perovskites can be achieved through halide mixing, but mixed halide perovskites are unstable under illumination due to halide phase segregation. Recent studies have found that iodoplumbate is selectively expelled from mixed halide perovskite grains, forming a separate I-rich phase, and proposed a mechanism based on reversible redox chemistry to explain this phenomenon.

Min Ji Hong et al.

Summary: In this study, the variability in electronic properties of metal halide perovskites was investigated using TRMC and SEM techniques to evaluate differences within samples and between different samples. The results demonstrate significant variations in electronic properties in samples prepared following different protocols, as well as in samples prepared following identical protocols.
