Revealing composition and structure dependent deep-level defect in antimony trisulfide photovoltaics
Abstract
Antimony trisulfide emerges as a suitable candidate for light-harvesting due to its good stability and abundance, yet the defect properties are not well-understood. Here, by means of deep-level transient spectroscopy, Lian et al. find that there are three kinds of deep-level defects depending on the chemical composition.
