Organic-inorganic hybrid perovskites (OIHPs) have recently emerged as groundbreaking semiconductor materials owing to their remarkable properties. Transmission electron microscopy (TEM), as a very powerful characterization tool, has been widely used in perovskite materials for structural analysis and phase identification. However, the perovskites are highly sensitive to electron beams and easily decompose into PbX2 (X = I, Br, Cl) and metallic Pb. The electron dose of general high-resolution TEM is much higher than the critical dose of MAPbI3 , which results in universal misidentifications that PbI2 and Pb are incorrectly labeled as perovskite. The widely existed mistakes have negatively affected the development of perovskite research fields. Here misidentifications of the best-known MAPbI3 perovskite are summarized and corrected, then the causes of mistakes are classified and ascertained. Above all, a solid method for phase identification and practical strategies to reduce the radiation damage for perovskite materials have also been proposed. This review aims to provide the causes of mistakes and avoid misinterpretations in perovskite research fields in the future. This article is protected by copyright. All rights reserved.

有机-无机杂化钙钛矿材料TEM表征中的错误识别分析

有机-无机杂化钙钛矿（OIHPs）由于其卓越的性能，最近已成为开创性的半导体材料。透射电子显微镜（TEM）作为一种非常强大的表征工具，已广泛应用于钙钛矿材料的结构分析和相识别。然而，钙钛矿对电子束高度敏感，容易分解成 PbX2 (X = I, Br, Cl) 和金属 Pb。一般高分辨率 TEM 的电子剂量远高于 MAPbI3 的临界剂量，这导致普遍错误识别 PbI2 和 Pb 被错误地标记为钙钛矿。广泛存在的错误对钙钛矿研究领域的发展产生了负面影响。这里总结并纠正了最著名的 MAPbI3 钙钛矿的错误识别，然后对错误的原因进行分类和确定。最重要的是，还提出了一种用于相识别的固体方法和减少钙钛矿材料辐射损伤的实用策略。本综述旨在提供错误的原因并避免未来钙钛矿研究领域的误解。本文受版权保护。版权所有。
