With continuous research and development, lead-free pure inorganic perovskites are expected to play an important role in the future of solar energy technology, potentially complementing or even replacing present technologies.
Tin-based halide perovskite materials have been successfully employed in lead-free perovskite solar cells. Recently, several studies have revealed that the substitution of the methylammonium cation by cesium (Cs) in the perovskite structure could significantly enhance its thermal stability. (6)
It is remarkable that the PCE of 10.1% is the highest one among all of the lead-free all-inorganic perovskite solar cells reported so far. (12,13) The aforementioned considerations provide the rationale for the study of B-γ-CsSnI 3 as a promising inorganic, lead-free, thermally stable perovskite for next-generation PSCs.
Organic–inorganic metal halide perovskite solar cells (PSCs) have attracted extensive attention from the photovoltaic (PV) community due to their fast-growing power conversion efficiency from 3.8% to 26.7% in only 15 years. However, these organic–inorganic hybrid PSCs suffer from inferior long-term operation Perovskites
Replacing the toxic lead in the state-of-the-art halide perovskite solar cells is highly desired but the device performance and stability are usually compromised. Here Chen et al. develop inorganic cesium tin and germanium mixed-cation perovskites that show high operational stability and efficiency over 7%.
To address these challenges, the design of all-inorganic lead-free halide perovskites offers potential solutions for photovoltaic applications. Here, two layered perovskite derivatives, Rb 3 Mo 2 Cl 9 and Rb 3 Mo 2 Br 9, are explored, and their electronic, structural, and photovoltaic properties are analyzed using advanced theoretical calculations.
