硫系钙钛矿作为光伏和光电应用的有前途的半导体，最近获得了研究关注。除了围绕这些材料的合成和加工成器件的挑战之外，它们在钙钛矿结构中的相稳定性是一个开放的研究问题。目前报道的合成缺乏明确的相稳定性标准。在这项工作中，我们提出了一个令人信服的相稳定性分析的硫化物ABS3和硒化物ABSe3化合物的离子半径和电负性参数的基础上。该分析用于筛选感兴趣的潜在材料，并激发对几种新的钙钛矿组合物的进一步实验研究。
Chalcogenide perovskites have gained recent research attention as a promising semiconductor for photovoltaic and optoelectronic applications. In addition to the challenges that surround the synthesis and processing of these materials into devices, their phase stability in perovskite structures is an open research question. Reported syntheses presently lack clear phase stability criteria. In this work, we present a compelling phase stability analysis of sulfide ABS3and selenide ABSe3compounds on the basis of ionic radii and electronegativity arguments. This analysis is used to screen potential materials of interest as well as motivate further experimental research into several new perovskite compositions.
