“…Therefore, recent PSC-based researchers have focused on improving the stability as well as the efficiency [ 103 , 104 ]. Studies have been performed to enhance the crystallinity, using inorganic ions [ 105 , 106 , 107 ], additives [ 108 , 109 , 110 ], new ETLs or HTLs [ 111 , 112 ], and interlayers [ 113 , 114 ].…”

Metal-organic frameworks (MOFs) and MOF-derived materials have been used for several applications, such as hydrogen storage and separation, catalysis, and drug delivery, owing to them having a significantly large surface area and open pore structure. In recent years, MOFs have also been applied to thin-film solar cells, and attractive results have been obtained. In perovskite solar cells (PSCs), the MOF materials are used in the form of an additive for electron and hole transport layers, interlayer, and hybrid perovskite/MOF. MOFs have the potential to be used as a material for obtaining PSCs with high efficiency and stability. In this study, we briefly explain the synthesis of MOFs and the performance of organic and dye-sensitized solar cells with MOFs. Furthermore, we provide a detailed overview on the performance of the most recently reported PSCs using MOFs.

“…[ 123 ] Hence it is speculated that SCN − shields Sn 2+ and significantly improves the film stability towards oxygen (Figure 15C, D and E). In addition, it uniformizes the grain of the perovskite film and reduces the amounts of pinholes, [ 124 ] leading to enhanced photovoltaic performance of Sn‐based perovskite PSCs. [ 125,126 ] Owing to the nearly same size of I − (220 pm) and SCN − (215–220 pm), [ 127 ] partial I − of [SnI 6 ] 4− framework are substituted by SCN − .…”

“…In reduced lead perovskite, I − anion fully reacts with Pb 2+ to generate PbI 2 due to vanished Pb(SCN) 2 peaks in XRD of FASnI 3 films containing Pb(SCN) 2 . [ 124 ] That's to say, the SCN − anion is more apt to form ionic bonding with the A‐site cation than the I − anion. [ 122 ] The addition of 5 mol% FASCN in a quasi‐2D FASnI 3 perovskites leads to a champion PCE of 8.17% [ 123 ] while 0.25 mol L −1 of Pb(SCN) 2 in 3D FASnI 3 obtains a PCE of 8.44%.…”

Recently, lead halide perovskites have attracted great attention in photovoltaic field because of high power conversion efficiency. However, the toxicity of lead in perovskite can result in environment issues, which are the major challenge for commercial application. In this context, environmentally friendly lead‐free perovskite alternatives are highly desired. Bearing excellent photophysical and electronic properties, tin‐perovskites (ASnX3) are the most promising alternative. In reality, extensive efforts have been committed to the development of Sn‐based perovskite solar cells. In this review, we summarized the theoretical fundamentals of Sn‐based perovskites, including lattice, phases, molecular orbital, redox property, and defects. Then varieties of tactics to improve devices performance were detailed reviewed. Finally, perspectives on further research directions in improving Sn‐based solar cells performance are presented.

“…discussed the effect of Pb(SCN) 2 additives in FASnI 3 perovskites. [ 82 ] FASnI 3 perovskite precursors with different Pb(SCN) 2 concentrations were synthesized. Then a high efficiency of 8.4% was achieved for FASnI 3 PSCs with 0.25 M Pb(SCN) 2 , which is significantly higher than that (1.6%) of PSCs without Pb(SCN) 2 .…”

Organic‐inorganic halide perovskite solar cells (PSCs) have drawn tremendous attention as their power conversion efficiency (PCE) has soared to 25.2%. Yet the most efficient halide perovskite materials all contain the toxic element lead (Pb). The search for an alternative element is a crucial research direction. Among all candidates, tin (Sn) appears to be the most promising one for its nontoxicity and physical similarity to lead (Pb). Herein, we review and summarize recent advancements in this emerging research area of Sn‐based perovskites. First, we discuss the photophysical dynamics of the Sn‐based perovskites and the relatively high efficiency of corresponding PSCs and other applications. Then, the attention is focused on the fabrication process and methods to improve the performance of Sn‐based photovoltaic devices. Despite the fact that the stabilities of the materials and related devices are far from perfect, the Sn‐based perovskites are still the best candidates with vast potential among all the Pb‐free perovskites for PSC application.
