“…These devices are cost-effective, solution processable, and composed of earth-abundant elements; thus, they demonstrate excellent potential for large scale solar electricity generation. Notably, different types of third-generation PV technologies exhibit different flaws, such as poor stability and toxicity (in Pb-based perovskite solar cells) and photodegradation (in organic solar cells). − …”

Their unique quasi one-dimensional (Q1D) crystal structure and rapid power conversion efficiency (PCE) evolution evoke tremendous scientific and technological interest in antimony chalcogenide (Sb2X3, X = S, Se, or S x Se1–x ) photovoltaics (PVs). Solution processability, strong photon harvesting, readily tunable optoelectronic properties, exceptional physicochemical stability, nontoxicity, and earth-abundance are their key features, endorsing Sb2X3 as next-generation PVs. Benign, self-healing grain boundaries and defect-tolerance add to their merits, empowering Sb2X3 films to act like pseudo-single crystals. These semiconductors are born for flexible PVs, as their Q1D crystal structures aid ultrahigh flexibility and bending tolerance. Sb2X3 solar cells are efficient in recycling indoor and ambient light; thus, they are promising as indoor PVs (IPVs). Sb2X3 PVs exhibit potential to simultaneously solve the stability and toxicity issues faced by lead halide perovskite PVs and the cost issues faced by mainstream silicon PVs. Presently, a record certified PCE of 10.7% has been demonstrated by Sb2X3 solar cells; thus, they are emerging as a promising low-cost alternative to the commercially available PV technologies. This review presents a unique perspective of the fundamentals, recent breakthroughs, challenges, and futuristic developments in this field, offering a fundamental guideline for the rational engineering, design, and fabrication of high-PCE Sb2X3 solar cells. This review highlights Sb2X3 based, large area, tandem, and flexible solar cells and explores the commercial viability of this technology from generic power production to niche markets.

“…Although the organic-inorganic halide perovskites have shown their potential in terms of high PCEs, when it comes to stability, the PSCs with organic content show poor stability toward various environmental conditions. [9][10][11][12] In this review, we have discussed the progress made toward the development of such PSCs that are free from any organic content. We have discussed in extensive detail the work done so far for different all-inorganic perovskite materials, their performance, and stability under different environmental conditions.…”

Summary Organic‐inorganic perovskites have proven to be outstanding solar cell light‐absorbing materials due to their spectacular properties such as high tolerance to defects, bandgap tunability, high carrier mobility, long diffusion length, and high absorption coefficient. However, the associated stability issues in harsh conditions hinder their commercial prospects. In addition to the instability of the absorbing perovskite layer, the usage of organic transport layers and its vulnerable interface with the absorbing layer also contributes to the overall instability of the device. Taking a cue from inorganic solar cell counterparts, researchers have now turned their attention to the development of inorganic perovskites to improve the stability of perovskite solar cells (PSCs). Work in this direction has led to power conversion efficiency (PCE) beyond 19% with improved stability. Here, we review the progress made toward the development of all‐inorganic perovskite materials and their integration into PSCs as stable absorbers. We have discussed in extensive detail the work done so far for different inorganic perovskite materials, their associated device performance, and stability. Besides this, we have also discussed the integration of inorganic transport layers in PSCs replacing the organic counterparts used traditionally and their effect on the stability of the device. The stability of all‐inorganic PSCs under different harsh environmental conditions has also been discussed in detail. Finally, we have presented a summary and outlook on the realization of all‐inorganic efficient and stable PSCs toward their commercial adaptability.

Summary The CsxFA1−xPbI3 perovskites are promising materials for photovoltaic applications owing to their high absorption coefficient and stability. However, the CsxFA1−xPbI3 films contain a high percentage of FA+ suffer from split phase and high trap states, leading to inferior photovoltaic performance. Hence, a template‐assisted technique basing on two‐stage intramolecular exchanges was developed to suppress phase separation as well as get desirable high quality CsxFA1−xPbI3 perovskite film. The as‐prepared colloidal CsI‐PbI2 film is treated with FAI solution before annealing. The obtained CsxFA1−xPbI3 perovskite thin layer displays a superb absorption edge beyond 830 nm and highly uniform enlarged grains with reduced grain boundaries or defects. Meanwhile, the improved morphology attributes to substantially increased photon‐induced electron‐hole pairs and corresponding collection efficiency which was testified by the external quantum efficiency measurements. The perovskite solar cells fabricated by this method presented power conversion efficiency of 18.5%.
