“…[126] As stated previously, the Cs 3 Sb 2 Br 9 NCs showed excellent air stability, and the absorption in ambient conditions showed only a slight variation over 30 days. [126] A completely different approach was adopted by Hong et al for the synthesis of the perovskite material without using any wet chemistry techniques. [127] They employed mechanochemical methods such as ball milling.…”

Perovskite solar cells (PSCs) have opened a floodgate of diverse research. These highly functional materials have immense potential prospects in renewable energy, optoelectronic applications, to name a few. Most of the perovskites have lead (Pb) as an integral active component. Though the Pb‐based organometallic perovskites have shown outstanding performance (over 25%), significant challenges exist including the presence of Pb, its toxicity as well as the instability that can hamper the use of these devices toward practical applications. There are some instances where a complete absence of Pb has been used to achieve respectable device performance, but they face a challenge from the towering success of their counterparts. To offset the issues, significant efforts are being carried out to employ other alternatives (cations) in conjunction with Pb, without distorting the inherent material properties. To that end, tin (Sn) has emerged as a promising alternative to Pb in achieving benchmark performance. Bringing these Sn PSCs into more prominence is a crucial step in taking low Pb or Pb‐free PSCs to the next level of research and commercialization. In this topical review, the notable advancements are highlighted, overviewed and recommendations are made for prospects toward environmentally friendly Sn‐based perovskite photovoltaics.

“…Due to the similar radius and the same valence state to Bi 3+ , Sb-based perovskite Cs 3 Sb 2 X 9 exhibits similar optical performance. [53,176,178] Ma et al demonstrated a LARP method to synthesize Cs 3 Sb 2 Br 9 PQDs with PL emission peaks covering the entire visible region [176] (Figure 11a,b). As shown in Figure 11d, the structure of Cs 3 Sb 2 X 9 can be derived from the standard perovskite CsSbBr 3 through removing every third Sb layer along c) Absorption spectra of Cs 3 Sb 2 X 9 PQDs.…”

“…Zhang et al 47 demonstrated a 2D Ruddlesden‐Popper type (C 18 H 35 NH 3 ) 2 SnBr 4 MHP with a strong PL emission at 625 nm, whose PLQYs in the colloidal suspension and the film reached 88% and 68%, respectively. Gan et al 48 reported a Sb‐based MHP of Cs 3 Sb 2 Br 9 , which shows a PL emission in the blue region centered at 470 nm with the FWHM of 63 nm. The Cs 3 Sb 2 Br 9 NCs display high stability when immersed in a polar solvent like ethanol.…”

Metal halide perovskites (MHPs) have been developing rapidly in recent years due to their outstanding optoelectronic properties and tremendous contributions from worldwide researchers. The external quantum efficiencies of perovskite light-emitting diodes (Pero-LEDs) have all exceeded 20% for the green, red, and near-infrared emitting ones. However, the toxicity and instability issues of the lead-based MHPs are still big problems limiting their practical applications. The applications of the lead-free MHPs (LFMHPs) are emerging as one of the most promising strategies to tackle these issues. Compared with lead-based MHPs, the LFMHPs show better environment stability and broader emission regions from the violet to near-infrared wavelength. Thanks to numerous contributions made by the researchers, great progress has already been made for the LFMHPs. For example, the photoluminescence quantum yield has reached near 100%. However, the performances of the lead-free Pero-LEDs are still lagging compared with their lead-based counterparts. In this review, we comprehensively summarize the synthesis developments of LFMHPs and their applications in the down-conversion white LEDs and electroluminescent Pero-LEDs. Moreover, some suggestions and outlooks of the lead-free Pero-LEDs developments are proposed in the end.
