“…The stability challenge in organic–inorganic hybrid lead halide perovskites solar cells is being addressed through low-toxicity Pb-free materials. Much like the Pb-containing perovskites, the desirable attributes for such Pb-free systems would be suitable direct bandgaps, high absorption coefficients, high mobilities, low exciton binding energies, long charge carrier lifetimes, etc. ,,− Fortunately, some of these materials discussed above do provide such attractive attributes, e.g. as in Sn/Ge-based halides, some double perovskites, and some Bi/Sb-based halides with perovskite-like structure.…”

With rapid progress in the deployment of metal halide perovskites in various device applications such as solar cells, light-emitting devices, field-effect transistors, photodetectors, etc., the next eminent focus is on the single crystals of these materials. With a lack of grain boundaries and low trap densities, remarkably long charge carrier diffusion lengths, and high ambient and operational stabilities, this class of materials seems greatly promising. Yet, the growing concern for lead toxicity in commercial semiconductor devices has entailed a thrust in the research of alternative lead-free perovskites, including their single crystalline forms. However, there is still no consolidated account of the state-of-the-art in this domain and accordingly, countless feasible systems still remain unexplored. To bridge this gap, we attempt to provide here, an up-to-date overview of lead-free perovskite single crystals with respect to their synthesis methods, structural diversity, stability, photophysical and electrical properties, and device applications. We discuss various approaches to designing, modeling, fabricating, and characterizing new single-crystal systems and conclude with some critical insights for further investigating this field of research.

“…On the one hand, in order to eliminate the toxicity of perovskite materials, the use of tin, silver, bismuth, indium, copper, etc., instead of lead for fabricating PSCs has also been well developed in recent years. [190][191][192][193][194] Chu et al used a Lewis base indacenodithiophene-based organic acceptor (ITIC) to improve the morphology and optoelectronic properties of Cs 3 Sb 2 I 9 -based solar cells. The optimal Cs 3 Sb 2 I 9 /ITIC heterostructure-based devices obtained a PCE of 9.2% under 1000 lux illumination.…”

“…Hu et al fabricated the bulk-heterojunction perovskite active layers consisting of phase-separated Cs 3 Bi 2 I 9 and Ag 3 Bi 2 I 9 to improve the grain orientation and interface band alignment [ 77 ], achieving a record efficiency of about 3.6% with a high V OC reaching 0.89 V for Bi-based PSCs. Singh et al used the indacenodithiophene-based organic acceptor with Lewis base groups to improve the morphology of wide-bandgap Cs 3 Sb 2 I 9 perovskites and enhance the electron-extraction ability in Sb-based PSCs [ 78 ], yielding a PCE of 3.25% for the inverted-structure device.…”

Perovskite solar cells (PSCs) emerging as a promising photovoltaic technology with high efficiency and low manufacturing cost have attracted the attention from all over the world. Both the efficiency and stability of PSCs have increased steadily in recent years, and the research on reducing lead leakage and developing eco-friendly lead-free perovskites pushes forward the commercialization of PSCs step by step. This review summarizes the main progress of PSCs in 2020 and 2021 from the aspects of efficiency, stability, perovskite-based tandem devices, and lead-free PSCs. Moreover, a brief discussion on the development of PSC modules and its challenges toward practical application is provided.
