Lead-free halide double perovskites with diverse electronic structures and optical responses, as well as superior material stability show great promise for a range of optoelectronic applications. However, their large bandgaps limit their applications in the visible light range such as solar cells. In ...
Lead‐free halide double perovskites (HDPs) sharing similar crystal structures with OIHPs, are promising candidates for optoelectronic applications. Meanwhile, HDPs possess unique properties that are uncommon in OIHPs deriving from feasible component engineering and strong electronphonon interaction. Bright ...
However, the number of synthesized halide double perovskites is limited, and more limited materials have been developed for optoelectronic applications to date. In addition, the band structures and carrier transport properties of the materials are still not desired, and the films still manifest low ...

In the present study the structural stability along with electronic, elastic, thermoelectric and optical properties of inorganic halide double perovskites have been calculated. Both the materials are stable in cubic structure follow the space symmetry of the Fm-3m space group. The stability in the Fm...
Lead halide perovskites have attracted extensive attention in recent years because of their excellent photoelectronic properties, such as high absorption coefficients, carrier mobilities, defect tolerances, and photoluminescence efficiencies. However, a key issue hindering their commercial application is the tox...
Illumination consumes more than 20 percent of electricity. Thus, finding an efficient, stable, single-phase warm white-light material is very important. Lead hybrid perovskites have drawn interest for excellent photoelectric performance and simple synthe
