“…ICAR 2022 Special Issue over 22% at the present time in only a few short years [4,5,6]. The exceptional performance of metal halide perovskites may be attributed to their unique properties, which include high charge carrier mobilities [7], controlled electron and hole transport [8], high absorption coefficients [9,10,11], direct and adjustable band gaps [12,13,14], and long carrier diffusion lengths [15].…”

“…It is anticipated that double perovskite elpasolites will also be used in thermal neutron scintillator material applications [22,25]. As can be seen in Figure (5), each of the BX6 octahedra is located on its own inside the perovskite crystal, making it a 0-dimensional (0D) perovskite. Because the combination of Cs2AgBiBr6 in Figure (4a) does not include enough Ag atoms to generate Cs2AgBiBr6, the BiBr6 octahedra are separated from one another in the crystal, and A site cations fill the cub-octahedral gaps.…”

“…The bismuth dpoint of double perovskites serves as the starting point for the incorporation of tetravalent cations into 4 + /0 double perovskites. For vacancy-ordered double perovskites, the usual formula is A2BvX6, where v stands for empty locations corresponding to the B' site for the A2BB'X6 double, as shown in Figure (5). There have been reports of structural models for Cs2SnI6 including 0-dimensional perovskite structures.…”

This study is an emphasis on the metal halide perovskite solar cells that are susceptible to factors that influence their power conversion efficiency (PCE). Perovskite solar cells, also known as PSCs, have been shown to have a high power conversion efficiency (PCE) due to a number of various factors. As they reached a power conversion efficiency of 25%, solar cells based on metal halide perovskite were a game-changer in the quest for photovoltaic performance. A flurry of activity in the fields of structure design, materials chemistry, process engineering, and device physics has helped the solid-state perovskite solar cell to become a leading contender for the next generation of solar energy harvesters in the world today. This follows up on the ground-breaking development of the solid-state perovskite solar cell in 2012. This cell has a higher efficiency compared to commercial silicon or other organic and inorganic solar cells, as well as a lower cost of materials and processes. However, it has the disadvantage that these high efficiencies can only be obtained with lead-based perovskites, which increases the cost of the cell. As a result of this fact, a new study area on lead-free metal halide perovskites was established, and it is now exhibiting a remarkable degree of vibrancy. This provided us with the impetus to review this burgeoning area of research and discuss possible alternative elements according to current theoretical and practical investigations that might be utilized to replace lead in metal halide perovskites as well as the features of the perovskite materials that correspond to these elements.

“…With lower bandgaps and remarkable stability, DPs Cs 2 NBiCl 6 (N = K, Rb, Cs) and Cs 2 NaBY 6 (B = Sb, Bi; Y = Cl, Br, I) showed promising optoelectronic applications [13,14]. Numerous papers have detailed the performance of Cs 2 CuNCl 6 (N = Sb, Bi) and related perovskites [15][16][17][18][19][20][21][22]. Over the past few years, thermoelectric technology has attracted much interest.…”

Recent studies have produced stable inorganic perovskites that contain no lead, replacing lead-containing perovskites' risky and unstable properties. The present investigation thoroughly examined the electrical behavior, elastic characteristics, optical features, and transport properties of Li2CuTlZ6 (Z = Cl, Br, I) halides in order to discover potential applications. The Wien2k code was utilized to apply density functional theory (DFT) in order to clarify these physical properties. Using the generalized gradient approximation (PBEsol-GGA), we determined structural parameters through the energy optimization procedure that corresponded with the available data. Additionally, elastic parameters as well as formation energies ranging between -2.33 to -1.39 eV were used to validate cubic durability for the two halides. Moreover, the modified Becke-Johnson (mBJ) potential successfully provided precise direct bandgap values for all halides. According to this study, the shift in anions from Cl to Br is responsible for the reduction in band gap within the infrared spectrum. Our computed optical parameter findings show that Li2CuTlCl6 and Li2CuTlBr6 halides demonstrate excellent optoelectronic efficiency with low reflection, strong optical absorption, and conductivity. The investigation clarifies that the temperature-dependent character of the materials electrical transport properties is due to their very small bandgap. These materials may find use in thermoelectric applications, as evidenced by the almost unity of the obtained figure of merit, which points to their semiconducting behaviour.

“…Recently, halide perovskite materials have been flourishing in the field of scientific research due to their applications in electronic devices as solar cells [1][2][3][4], light-emitting diodes (LED) [5][6][7][8], photo-detectors [6,9], and laser applications [10][11][12][13][14]. This is due to the unique properties of these materials such as the long of charge carrier diffusion length [9,13,15] high charge carrier Mobility [15,16], high photoluminescence quantum yield (PLQY) [11][12][13]17], large absorption spectrum [4,6,9,18,19], high absorption coefficient [8,20], and a tunable energy band-gap via adding the impurities [3,6,15,21].…”

In the double perovskites structures, Cs2SbAgX6, X is I, Br, or Cl, the structural, electronic, thermodynamic, thermoelectric and optical, properties have been investigated by using the density functional theory (DFT) correction method. The XRD structural study exhibits that the double perovskite structures are stable in the cubic phase structures. Elastic parameters reveal all structures to be very hard and ductile in nature. The energy band profiles display indirect band-gap of semiconductor behavior for the structures Cs2SbAgX6; X is Cl or Br, while exhibiting metallic behavior of the structure Cs2SbAgI6. The thermoelectric transport properties were verified in the temperature range (5-1000) K, which includes electrical conductivity, thermal conductivity, Seebeck coefficients, and the figure of merit, ZT, for Cs2SbAgX6 structures. These structures exhibit high thermal conductivity with good Seebeck coefficients at room temperature. The semiconducting structure, Cs2SbAgBr6, has appropriate band gaps and best Seebeck coefficients; therefore, it has the best values of ZT reached 0.00016 at 1000K, which means the suitable structure for employment in thermoelectric and spintronic devices applications. The optical properties of these structures exhibit that the absorption effective region at the Visible-Ultraviolet region, therefore these materials are suitable in the applications of solar cells and optoelectronic devices.
