This study presents a theoretical exploration of a novel class of anisotropic Janus monolayer materials, BXY (with X being P, As, or Sb, and Y being S, Se, or Te), utilizing first-principles density functional theory. Our stability analysis reveal that the eight of these monolayers exhibit high stability, with the exception of BSbS. Through the application of the HSE06 hybrid functional, We’ve identified that these stable monolayers fall into the category of semiconductors with an indirect bandgap, and their band gaps span a range between 0.35 and 3.00 eV. Except for BSbSe, all other semiconductors fulfill the band edges criteria in photocatalytic water splitting. Additionally, we have observed that these materials possess anisotropic and superior carrier mobility and optical absorption properties, attributed to their distinct anisotropic structure. As for the solar-to-hydrogen (STH) efficiency, five of these monolayers exhibit STH efficiencies that go beyond the 10 %, with BAsS and BSbTe reaching notable values of 33.93 % and 36.11 %, respectively. Furthermore, the synergistic effects of photoexcitation and electrocatalysis in these monolayers facilitate the overall water splitting process. Additionally, we explored how uniaxial and biaxial strain impact the electronic, optical absorption, OER, and HER activity, as well as the STH efficiency, of these stable monolayers. We found that a small range of uniaxial strain (−2% to 2 %) can enhance their STH efficiency.

In this study, we have developed a self-powered heterojunction photovoltaic detector based on ZnO:B/Sb₂Se₃ through a combination of theoretical and experimental methods. Utilizing a close-spaced sublimation technique, we grew highly (002)-oriented high-light-sensitive Sb₂Se₃ on a wide-bandgap ZnO:B substrate to form a high-performance heterojunction. The multifunctional ZnO:B serves not only as an n-type layer forming a heterojunction structure for self-power generation but also acts as a transparent front electrode, streamlining the device structure. Simultaneously, through theoretical simulations, we investigated the impact of Sb₂Se₃ defects, interface defects, as well as the thicknesses of the ZnO:B layer and MoO₃ layer on the device’s performance. Notably, when the electron affinity of 4.1 eV in the ZnO:B layer minimizes the electron transport barrier for the Sb₂Se₃ layer, it results in the lowest carrier recombination rate and highest photocurrent density in the Sb₂Se₃ photovoltaic detector. The PCE of the photovoltaic detector has also reached its maximum. In addition, we determined the optimal thickness for the Sb₂Se₃ absorber, which varies with the monochromatic wavelength from 400- to 900-nm. Notably, longer wavelengths necessitate thicker absorbing layers. The longer the incident wavelength, the greater the impact of defect density on the device. Our exploration of the theoretical performance of the Sb₂Se₃ photovoltaic detectors revealed its exceptional detection capability at a wavelength of 700-nm, achieving a theoretical responsivity of 504.64 mA·W⁻¹, a detectivity of 1.34 × 10²⁰ Jones, and an on/off ratio of 1.14 × 10¹⁷.

Specifically, the ETL/perovskite interface contains defects such as iodine vacancies. Meantime, the Fermi energy (<em>E</em>_F) level of ETL is generally much higher than ones of perovskite and transparent conductive oxide (TCO) electrode. The above two issues together contribute to serious charge carrier recombination in devices. Oxyacid salts have been developed to be promising interfacial materials for ETL/perovskite interface, owing to their effective defect passivation and energy level tuning. However, the structure-functionality relationship of these materials has not been well established due to the unclear correlation between interfacial interaction and energy level tuning. Herein, through using CdSO₄ as modifier for TiO₂ ETL and controlling the thickness, we investigate the interfacial interaction and successfully correlates it to energy level tuning.
