Summary: The electronic structure, optical properties, and photocatalytic performance of the SiS/BSe heterostructure were investigated by first-principles calculations. The SiS/BSe heterostructure was found to be energetically and thermally stable in the ground state. The band gap of the SiS/BSe heterostructure was reduced compared to the constituent monolayers, suggesting enhanced optical absorption. Moreover, the heterostructure exhibited type-II band alignment, making it a promising candidate for photogenerated charge separation and light detection. The absorption spectrum of the SiS/BSe heterostructure showed broadening and red-shift. Additionally, the heterostructure had suitable band edges and standard redox potentials, making it a potential candidate for photocatalytic water dissociation under solar light irradiation. These findings pave the way for practical applications of the SiS/BSe heterostructure in optoelectronics and photocatalysis.

Summary: This article presents a theoretical model of hydrogen-related reactions with impurities in n- and p-type solar-grade silicon. It addresses reactions with dopants and carbon that are relevant to the degradation of silicon solar cells, particularly in light- and elevated temperature-induced degradation. The article highlights the comparative study of hydrogen molecule dissociation in B- and Ga-doped material, the subsequent formation of acceptor-hydrogen pairs, the proposed mechanisms explaining the kinetics of photo-/carrier-induced dissociation of PH and CH pairs in n-type Si, the analysis of reactions involving interactions between molecules with P and C, and the identification of electron and hole traps using atomistic- and wavefunction-resolved models. The thermodynamics of several reactions involving hydrogen with group-III acceptors in silicon is also investigated. Overall, the results provide a first-principles-level understanding of thermally and carrier-activated processes relevant to degradation of Si-based solar cells.

Summary: One effective strategy for improving the photocatalytic activity of composite materials is to construct a heterostructure using layered double hydroxide (LDH) as the main photocatalytic material. In this study, a novel flower-like spherical photocatalytic composite, ZnCdS/Bi2WO6/ZnAl-LDH, with a dual type II heterostructure, was prepared by a hydrothermal method. The composite exhibited a significantly broader light absorption range and a more uniform pore size distribution compared to ZnAl-LDH. It was found that a composition with 20% ZnCdS displayed the highest photocurrent density, the lowest electron-transfer resistance, and the lowest electron-hole recombination efficiency. The ZnCdS/Bi2WO6/ZnAl-LDH composite showed good photocatalytic degradation ability and enhanced hydrogen production, which remained stable after three experimental cycles. Trapping experiments identified the active species involved in the photocatalytic reaction and suggested the presence of a dual type II heterostructure in the composite.

Summary: In this study, the photoelectrochemical activity of nitrogen-doped titanium dioxide thin-film was investigated using experiments and first principle density-based calculation. It was observed that the band-gap of N-TiO2 reduced due to hybridization of N 2p with O 2p and localized valence band upshifting. The experimental results showed that the nanostructured partially crystalline nitrogen-doped titanium dioxide photoelectrode exhibited high photoelectrochemical response, which can be attributed to the abundance of hydroxyl groups, high electrochemical active surface area, and reduced charge transfer and recombination rates.

Summary: Type-II heterostructures of 2D semiconductor materials have shown promise in addressing the environmental crisis. This study demonstrates the stability and photocatalytic properties of ZnO/Ga2SSe and ZnO/GaSe heterostructures through DFT calculations. The theoretical results confirm their compatibility with photocatalytic water splitting. The Gibbs free energy in the redox process confirms the thermodynamic spontaneity of oxygen reactions in both heterostructures. The ZnO/Ga2SSe heterostructure, specifically, shows potential for spontaneous hydrogen evolution. Furthermore, strain tuning enhances the absorption performance of the ZnO/Ga2SSe heterostructure and significantly improves its solar hydrogen efficiency (STH) compared to pristine ZnO and Ga2SSe. In conclusion, the ZnO/Ga2SSe heterostructure holds promise as a prospective substitute material for water splitting.
