Hybrid organic–inorganic halide perovskites (HOIPs) have recently represented a material breakthrough for optoelectronic applications. Obviously, studying the interactions between the central organic cation and the Pb-X inorganic octahedral could provide a better understanding of HOIPs. In this work, we used a first-principles theoretical study to investigate the effect of different orientations of central formamidinium cation (FA+) on the electronic and optical properties of FAPbBr3 hybrid perovskite. In order to do this, the band structure (with and without spin–orbit coupling (SOC)), density of states (DOS), partial density of states (PDOS), electron density, distortion index, bond angle variance, dielectric function, and absorption spectra were computed. The findings revealed that a change in the orientation of FA+ caused some disorders in the distribution of interactions, resulting in the formation of some specific energy levels in the structure. The interactions between the inorganic and organic parts in different directions create a distortion index in the bonds of the inorganic octahedral, thus leading to a change in the volume of PbBr6. This is the main reason for the variations observed in the electronic and optical properties of FAPbBr3. The obtained results can be helpful in solar-cell applications.

“…As the temperature increases to about 50 • C, the structure of HIPs takes a tetragonal phase with the space group P4/mbm, and at temperatures above 300 • C, they are in the original Coatings 2021, 11, 1173 2 of 13 cubic phase with the space group Pm3m. In hybrid perovskite structures, by changing the halogens from iodine to bromine and then chlorine, the BX 6 octahedral volume decreases, resulting in a reduction in total volume of the structures [85][86][87][88][89][90].To acquire a comprehensive knowledge of the electrical and optical properties of semiconductor compounds, the band structure, electron density, charge carrier mobility, density of states, and dielectric function must be investigated [91][92][93][94][95].…”

RETRACTED: The Effect of Structural Phase Transitions on Electronic and Optical Properties of CsPbI3 Pure Inorganic Perovskites

Hybrid inorganic perovskites (HIPs) have been developed in recent years as new high-efficiency semiconductors with a wide range of uses in various optoelectronic applications such as solar cells and light-emitting diodes (LEDs). In this work, we used a first-principles theoretical study to investigate the effects of phase transition on the electronic and optical properties of CsPbI3 pure inorganic perovskites. The results showed that at temperatures over 300 °C, the structure of CsPbI3 exhibits a cube phase (pm3m) with no tilt of PbI6 octahedra (distortion index = 0 and bond angle variance = 0). As the temperature decreases (approximately to room temperature), the PbI6 octahedra is tilted, and the distortion index and bond angle variance increase. Around room temperature, the CsPbI3 structure enters an orthorhombic phase with two tilts PbI6 octahedra. It was found that changing the halogens in all structures reduces the volume of PbI6 octahedra. The tilted PbI6 octahedra causes the distribution of interactions to vary drastically, which leads to a change in band gap energy. This is the main reason for the red and blue shifts in the absorption spectrum of CsPbI3. In general, it can be said that the origin of all changes in the structural, electronic, and optical properties of HIPs is the changes in the volume, orientation, and distortion index of PbI6 octahedra.

Replacing organic liquid electrolytes (LEs) in lithium‐ion batteries (LIBs) with solid‐state electrolytes (SSEs) to achieve all‐solid‐state lithium batteries (ASSLBs) with improved safety and potential higher energy density has been attracting growing attention for their wide application in various electronic devices, electric vehicles and renewable energy integration. To achieve high‐performance ASSLBs, the design of SSEs with high ionic conductivity, easy processability, and compatible and stable interfaces with the cathode and anode has become a research priority in recent years. Among all the challenges and issues concerning interfaces, the mechanisms and suppression methods of interfacial reactions are particularly important in the rational design of efficient electrolyte/electrode interfaces. This review mainly focuses on interfacial reactions in various types of inorganic ASSLBs and significant negative effects on battery performance. We also highlight advanced characterization methods and summarize some notable approaches to stabilize interfaces. Finally, we believe the scientific prospect of ASSLBs interface research will be helpful to keep pace with future research trends.
