Abstract

Constructing type-II heterojunctions with donor–acceptor or even S-scheme mechanism to constantly convert solar energy into storable energy is a desirable strategy to solve the global energy shortage. Here, the first-principles calculations show that γ-GeSe/blue phosphorene (BlueP) heterostructure possesses good stability and great potential in solar energy conversion applications. The moderate band gap, type-II band alignment, strong light absorption, and S-scheme charge transfer mechanism make γ-GeSe/BlueP heterobilayer a promising bifunctional material as water-splitting photocatalysts and solar cells, featured with a high power conversion efficiency of 18.27%. Furthermore, weak biaxial strains can effectively modulate its band structure, and therefore significantly improve the carrier mobilities and solar-to-hydrogen efficiency. These results suggest that γ-GeSe/BlueP heterojunctions are promising materials for efficiently converting solar energy into electricity and hydrogen.

期刊介绍： The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results. Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
