“…However, concerns about stability and toxicity cast a shadow over their efficiency. [ 36 ] Compared to the state‐of‐art stability of Si‐based solar cells, LHP solar cells are stable for only over a year. [ 25 ] On the other hand, recycling LHPs presents a significant challenge, raising questions about how to manage this process effectively.…”

Indoor photovoltaics (IPVs) have garnered significant attention in recent years due to their potential to empower small portable electronic devices and the Internet of Things (IoT). After silicon solar cells, it is now widely acknowledged that the dominant technology in the field of outdoor/indoor photovoltaics is hybrid lead (Pb) halide perovskites. Despite the fascinating characteristics of hybrid Pb‐halide perovskites, the presence of toxic Pb is regarded as one of the major factors that prevent commercialization. Low‐toxic, Pb‐free, and stable perovskites are also being used in outdoor solar cells (ODSCs), but their efficiencies are low due to large bandgap (i.e. ∽2.0 eV). Recently, some of the stable, Pb‐free perovskite materials have drawn great interest due to their initial performance across various fields, including light‐emitting diodes (LEDs), photodetectors, X‐rays, photocatalysis, ODSCs, and in IPVs. In this perspective, we summarized the current status and prospects for Pb‐free halide perovskites, chalcogen perovskites, silver bismuth halide (AaBbXa+3b) family, and other chalcogen materials are being explored to speed up the progress of IPVs.This article is protected by copyright.

“…[18,21,24] For example, DMAI and the derivative have been widely adopted as an additive for the high performance of CsPbI 3 solar cells, which slightly enhanced the stability of such devices, due possibly to the tensile strain caused by the oversized DMA þ ions in the A site. [25][26][27] However, others argue that DMAI may react with CsPbI 3 , forming double-cation hybrid perovskite Cs 1-x DMA x PbI 3 , which acted as a dopant instead of an additive. Nevertheless, the internal tensile strain caused by the oversized DMA þ ions has been proven beneficial for structural stability.…”

“…[33,34] They discovered that the organic long-chain branched ligands could stabilize the nanocrystals of the α-CsPbI 3 at room temperature, which is at the expense of the charge transport properties and the morphology of the nanocrystals, leading to a reduced PCE. [19,26] It is evident that the phase transition challenge is next to impossible to resolve, especially when the details of the thermodynamics and kinetics of the transition remained unclear.…”

Hindered Phase Transition Kinetics of α‐CsPbI₃ by External Tension

Recently, the all‐inorganic perovskite solar cells have attracted large amount of attention, due to the much better water resistance compared to the organic counterparts. Unfortunately, the undesired phase transition remained a significant challenge, despite the many attempts. An important step forward has been made here by numerical simulation, which discovered the significance of external strain to the stability of desired α‐CsPbI3, whose lifetime can be extended up to 3 times by non‐hydrostatic tension, as has been verified by both modelling and experimental results. In addition, such lifetime could be even enhanced further by hydrostatic tension, as indicated by the simulation. The unexpected observation provided not only an effective method to extend the lifetime of the perovskite devices, but also opened an unexpected path for the wide research community to utilise the straining engineering method that has been extensively investigated in the perovskite research.This article is protected by copyright.

“…For the above reasons, new Sb-based perovskite inspired materials (PIMs) have started to be developed and studied to potentially mitigate the problem of toxicity of Pb and of air instability of Sn-based materials. ,− Trivalent Sb-based perovskite PIMs have generally exhibited suitable chemical stability. ,− However, no solar modules have been reported for PIMs. We forecast that this superior basis provides the possibility for large-scale module fabrication, which is an important consideration for a technology with industrial potential …”

Perovskite-inspired materials (PIMs) have come to the fore recently because they aim to solve a main issue with perovskite technology, that of the potential toxicity of lead (Pb), as well as offer alternatives to tin (Sn)based perovskites, which are unstable. First, we introduced two cations in the precursor mixture, which improved power conversion efficiencies (PCE = 1.5%) of antimony (Sb)-based MA 1.5 Cs 1.5 Sb 2 I 3 Cl 6 solar cells by 81% compared to conventional Cs-only counterparts. ISOS-D-1 stability was also boosted by 60%, with a loss of only 10% after ∼1800 h of aging in the air. Stability over this many hours, accompanied by thermal durability of hundreds of hours at high temperatures of 85 °C in the air (ISOS-D-2), for these PIMs, also enabled us to carry out all three scalable P1, P2, and P3 laser patterning steps in air and demonstrate the first solar module (PCE = 1.2%) made with any kind of PIM.
