“…This strategic approach allows researchers to tailor the chemical composition and properties of perovskite materials, providing a pathway to mitigate environmental concerns associated with lead-based perovskites. The investigation into double perovskites represents a promising avenue for developing environmentally friendly and sustainable alternatives for use in various electronic applications, including solar cells (3)(4)(5)(6)(7)(8)(9). Hybrid double perovskites (HDPs) demonstrate remarkable compositional flexibility, primarily attributed to the extensive array of potential elements that can occupy the B' and B'' sites.…”

Perovskite materials hold promise for photovoltaic use due to their high efficiency, low cost, and versatility. However, challenges remain, including stability and environmental impact, but their potential to transform solar energy is significant. Lead-based perovskites have significantly boosted power conversion efficiency in photovoltaics, going from 3.8% to 33.3% in recent years. Lead-based perovskite materials have toxicity and stability issues, including sensitivity to light, heat, and moisture. Researchers are working on addressing these concerns, but they remain challenges for the technology. Therefore, the ongoing research focused on synthesizing lead-free perovskite materials for solar cells applications. We have synthesized MA2NaBiCl6 lead-free halide double perovskites material using one step cost effective hydrothermal method showing suitable tolerance and octahedral factors which signifies the stability of the material. We have fabricated the solar cell device based on as synthesized MA2NaBiCl6 as absorbing layer and Cu2O and ZnO as electron and hole transport layer respectively in the fabricated device. We have made contact of gold for good adhesion and characterize the solar cell device. The short circuit current density (JSC), open circuit voltage (VOC), fill factor (FF) and power conversion efficiency (PCE) of the solar cell device is found to be 4.01 mA/cm 2 , 0.97 V, 58 and 2.08% respectively. The calculated solar cell performance parameters are excellent in comparison to the reported solar cell device based on double perovskites materials which offers us a promising window for improving the sustainability of photovoltaic technology by addressing environmental and health concerns associated with lead.

In recent years, three‐dimensional (3D) lead‐free double halide perovskites have been considered promising candidates for photovoltaic applications due to their high stability and the use of non‐toxic materials, and the absence of organic materials in their structure. The structural, electronic, and optical properties of 3D double Halide perovskites Cs2CuBiBr6 and Cs2CuBiCl6 were investigated in this paper using first‐principles density functional theory (DFT) simulation with BLYP approximation. The results showed that structures Cs2CuBiBr6 and Cs2CuBiCl6 have an indirect band gap, high absorption coefficient, low reflection, and high conductivity. A redshift of absorption edge and band gap shrinkage has been observed in the Cs2CuBinormalX6 structure with an increase in the ionic radius of the halogen, which indicates the unique features of structure Cs2CuBiBr6 for photovoltaic applications, LED, laser, and other optoelectronic devices.

“…The crystal symmetry, phase formation, and purity were investigated with the help of X-ray diffraction (XRD) and the energy band gap of 4.11 eV was calculated using ultraviolet-visible light spectroscopy (UV-Vis). Therefore, there are a number of double perovskite compounds that have been synthesised and their properties were investigated using different techniques [18][19][20].…”

Double perovskite compounds (DPCs) have gained much more attention due to their versatile character in the fields of electronics and spintronics. Using density functional theory (DFT) we investigated the electronic, magnetic and optical properties of DPC La2BB′O6 where B = Cr, Sc and V and B′ = Co, Ni. The electronic band gaps suggest these compounds are half-metallic (HF) semiconductors in the spin-up channel and metallic in the spin-down channel. Magnetic properties suggest these are ferromagnetic in nature, so all DPCs are half-metallic ferromagnetic (HM-FM). Furthermore, the compound La2CrCoO6 shows outstanding electronic and optical properties, so it can be used in optoelectronic/spintronic devices.
