Modifying light-harvesting photoactive materials via doping and/or functionalization approaches is an effective approach for enhancing the efficiency and stability of solar cells. Herein, sulfur-functionalized two-dimensional (2D) transition-metal carbide (S-MXene) nanosheets are synthesized and introduced as doping agents into the Sb2S3 light absorbers for solar cells. Furthermore, Sb2S3 solar cells are fabricated in two different experimental environments including an inert gas (argon) and ambient conditions (air) using S-MXene as the dopant. Our theoretical calculations and experimental analysis revealed that the ambient air fabrication and incorporation of conductive S-MXene can lead to an increase in the charge transport of Sb2S3 solar cells as well as introduce a p-type doping effect. Moreover, the best-performing device with S-MXene fabricated in air exhibited significant enhancement (59.65%) in the performance with respect to the S-MXene-doped cells fabricated in a glovebox filled with an inert gas. This work not only introduces the possibility of ambient air fabrication of Sb2S3 solar cells but also opens an avenue toward the development of functionalized 2D dopants for Sb2S3 solar cells.

According to International Energy Agency (IEA), no investment in new fossil fuel supply projects will be made from today, while there will be no sales of new internal combustion engine passenger cars by 2035. [2] Renewable energy sources such as wind and solar energy are capable of generating around 70% of global electricity demand by 2050. [2] Solar photovoltaic (PV) technologies are of particular interest because the sun is the world's largest source of energy supply.Impressively, solar cells made of silicon (Si) semiconductors provide a combination of excellent PV performance and a long lifetime. Their commercial modules can last for more than 20 years, and therefore, mono-and poly-crystalline Si solar cells make up >90% of the PV market. [3] Notably, recent progress in PV sector has led to a considerable reduction in the module price of Si solar cells, but the overall systems still suffer from high installation costs (known as balance of system) which are accountable for 75% of the system cost. [4] Therefore, further developments are still in demand in order to maximize Perovskite solar cells (PSCs) have attracted a great deal of attention from the photovoltaic (PV) community because of their remarkable performance, low production cost, and high potential to be integrated into other optoelectronic applications. Despite their promise, the challenges associated with their operational stability have drawn increasing attention over the past decade. Owing to their unique structure and fascinating properties such as high charge mobility, excellent conductivity, tunable bandgap, good optical transparency, and optimal surface functionalization, nanostructured materials, in particular monoelemental 2D materials, have recently been demonstrated to play versatile functions in suppressing the degradation of PSCs and enhancing the PV performance of the devices. In this review, recent advances in perovskite solar cells employing monoelemental 2D materials are presented. A brief overview of perovskite light absorbers based PV devices is first introduced, followed by critical discussions on the use of various elemental 2D materials including graphene, phosphorene, antimonene, borophene, bismuthene, and their derivatives for different components of the perovskite solar cells. Finally, the challenges in this cutting-edge research area are highlighted, and the authors express their own perspectives on addressing these key issues.

Engineering the intermetallic nanostructures as an effective bifunctional electrocatalyst for hydrogen and oxygen evolution reactions (HER and OER) is of great interest in green hydrogen production. However, a few non‐noble metals act as bifunctional electrocatalysts, exhibiting terrific HER and OER processes reported to date. Herein the intermetallic nickel–antimonide (Ni─Sb) dendritic nanostructure via cost‐effective electro‐co‐deposition method is designed and their bifunctional electrocatalytic property toward HER and OER is unrevealed. The designed Ni─Sb delivers a superior bifunctional activity in 1 m KOH electrolyte, with a shallow overpotential of ≈119 mV at ‐10 mA for HER and ≈200 mV at 50 mA for OER. The mechanism behind the excellent bifunctional property of Ni─Sb is discussed via “interfacial descriptor” with the aid of Kelvin probe force microscopy (KPFM). This study reveals the rate of electrocatalytic reaction depends on the energy required for electron and proton transfer from the catalyst's surface. It is noteworthy that the assembled Ni─Sb‐90 electrolyzer requires only a minuscule cell voltage of ≈1.46 V for water splitting, which is far superior to the art of commercial catalysts.
