“…A randomly oriented ZnO layer can also be used as a buffer layer, which is reported to promote preferential , growth of (Sb 4 Se 6 ) n ribbons . Alternate strategies involve employing ETL bilayers (SnO 2 /CdS, TiO 2 /CdS, ZnO/TiO 2 , and TiO 2 /ZnS), ,, a carbon interlayer, an In 2 S 3 interlayer, and a ZnS interlayer . These strategies have been proven to be effective approaches for the deposition of uniform and pinhole-free Sb 2 X 3 films, passivation of interface defects, facilitating favorable band alignment improving the overall device performance.…”

“…It is worth noteworthy that high-PCE Sb 2 X 3 solar cells still employ (toxic) CdS as the ETL and Spiro-OMeTAD as the HTL. , Both these materials are well acknowledged to be the primary source of instability in Sb 2 X 3 solar cells and, thus, utterly need substitution. ZnS has shown promising results as a worthy substitute to CdS . While a CdS ETL works best for Sb 2 Se 3 solar cells, a SnO 2 ETL generally shows better performances in Sb 2 S 3 and Sb 2 (S/Se) 3 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.

Antimony sulfide is a promising photovoltaic material for the top subcell of Si‐based tandem solar cells due to its suitable bandgap, high absorption coefficient, low cost, and environmentally friendly properties. However, the electron transport layer (ETL) of antimony sulfide solar cells is generally based on CdS, while narrow‐bandgap CdS (Eg = 2.4 eV) absorbs part of the short‐wavelength light causing spectral loss. Unfortunately, Sb2S3 films could not be deposited uniformly on TiO2 substrate by the hydrothermal method. For the first time, reactive ion etching (RIE) treatment to TiO2 surface is developed to activate it for later Sb2S3 deposition. Based on this strategy, the obtained Sb2S3 film is almost the same as that deposited on CdS, smooth, dense, and uniform. The optimal device efficiency can reach 6.06%, a top value among TiO2/Sb2S3 devices with a new record of short‐circuit current density (≈19.4 mA cm−2). The high efficiency on RIE‐treated TiO2 ETL is attributed to the high transparency of TiO2 and the high‐quality Sb2S3 thin film with suppressed recombination in the Sb2S3 bulk film and TiO2/Sb2S3 interface. This work proposes a simple and efficient strategy for deposition of high‐quality Sb2S3 thin films on inert substrates.
