摘要
铅卤钙钛矿的毒性和稳定性仍然是当前待解决的研究难题,有必要寻求无毒、稳定的“神似”铅卤钙钛矿的新型光电材料。硫属钙钛矿ABX3(X=S,Se)由于高度稳定、组成元素丰富且无毒,具有良好的光学和电学特性,可用于各种光电材料,成为关注的焦点。当前研究最广泛的硫属钙钛矿BaZrS_(3)具有合适的直接带隙、优异的光吸收、良好的载流子传输性能、优异的化学稳定性和环境友好性,极具发展潜力。本文综述了BaZrS_(3)在理论计算、粉体及薄膜材料制备方面的最新进展,尤其对BaZrS_(3)的制备做了深入分析,并对BaZrS_(3)研究中的关键问题进行了分析和展望。本综述将为新进入这一领域的研究者提供重要借鉴,促进安全、稳定、环境友好的新一代光电材料的进一步发展。
Toxicity and stability of lead halide perovskite are still crucial problem to be solved,and it is necessary to seek nontoxic and stable new optoelectronic materials with similar structure of lead halide perovskites.Chalcogenide perovskite ABX3(X=S,Se)have become the focus of research recently for its high stability,non-toxicity and being abundant in earth element.ABX3(X=S,Se)also has good optical and electrical properties,and can be used in various photoelectric materials,making it suitable for various optoelectronic materials.The most widely studied material is chalcogenide perovskite BaZrS_(3).BaZrS_(3)has suitable direct bandgap,excellent light absorption,good carrier transport properties,excellent chemical stability and environmentally benign nature.This article reviews the latest progress in theoretical calculations,synthesis methods of powders and thin film of BaZrS_(3),especially gives in-depth analysis of the synthesis of BaZrS_(3).Key issues in the synthesis of BaZrS_(3)are discussed.This review will provide important references for new researchers entering this field and promote the further development of safe,stable and environmentally new generation optoelectronic materials.
