Perovskite solar cells employ lead halide perovskite materials as light absorbers. These perovskite materials have shown exceptional optoelectronic properties, making perovskite solar cells a fast-growing solar technology. Perovskite solar cells have achieved a record efficiency of over 20%, which has superseded the efficiency of Gräztel dye-sensitized solar cell (DSSC) technology. Even with their exceptional optical and electric properties, lead halide perovskites suffer from poor stability. They degrade when exposed to moisture, heat, and UV radiation, which has hindered their commercialization. Moreover, halide perovskite materials consist of lead, which is toxic. Thus, exposure to these materials leads to detrimental effects on human health. Halide double perovskites with A2B′B″X6 (A = Cs, MA; B′ = Bi, Sb; B″ = Cu, Ag, and X = Cl, Br, I) have been investigated as potential replacements of lead halide perovskites. This work focuses on providing a detailed review of the structural, optical, and stability properties of these proposed perovskites as well as their viability to replace lead halide perovskites. The triumphs and challenges of the proposed lead-free A2B′B″X6 double perovskites are discussed here in detail.

Perovskite solar cells have been investigated intensively due to their promising performance which increased significantly since it was found a few years ago. In this paper, we reported the computational results of electronic structures of lead-free halide perovskite material, Cs2SnI6. This perovskite has been much reported recently because of its properties as electron transport material. Its electronic structure was computationally calculated based on the Density Functional Theory (DFT) by using the Quantum Espresso computational package, implemented by using the Perdew-Burke-Ernzerhof (PBE) of scalar relativistic exchange-correlation functional and the HSE06 hybrid functional. The calculation results show that Cs2SnI6 has a direct bandgap of 0.28 eV and 0.82 eV for the calculation by using PBE and HSE06, respectively. The calculation using HSE06 results produce a closer result to the experimental data.
