Here, we demonstrate that MAPbI\n                    <jats:sub>3<\/jats:sub>\n                    single crystals exhibit a unique combination of hierarchical defense to water and self\u2010healing capability, with their skeleton structure nearly unaffected by water. The crystals maintain structural integrity for over one month while floating on water and show a reversible black\u2010to\u2010yellow\u2010to\u2010black phase transition. Surface hydration reverses by natural drying, while bulk hydration can be completely recovered by solvent immersion. The surface microstructure enhanced hydrophobicity and the inherently water\u2010resistant (110) facet play key roles in blocking water ingress. Even upon water invasion, the crystal forms a hydrate that preserves the critical [PbI\n                    <jats:sub>6<\/jats:sub>\n                    ]\n                    <jats:sup>4\u2212<\/jats:sup>\n                    octahedral framework, providing the structural basis for subsequent dehydration and self\u2010healing. The devices with the self\u2010healed crystal have 98% efficiency of the devices with the original crystal, and they maintain 90% efficiency after 1300 and 2000\u00a0h in air, respectively. This work demonstrates the exceptional water tolerance of perovskite single crystals, promising long\u2010term stable optoelectronic devices.\n                  <\/jats:p>","DOI":"10.1002\/smtd.70985","type":"journal-article","created":{"date-parts":[[2026,8,22]],"date-time":"2026-08-22T04:19:16Z","timestamp":1787372356000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hierarchical Defense and Self\u2010Healing Make Perovskite Single Crystals Impervious to Water"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5276-4545","authenticated-orcid":false,"given":"Hongzhong","family":"Deng","sequence":"first","affiliation":[{"name":"Shenzhen Key Laboratory of New Materials Technology School of Materials Science and Engineering Harbin Institute of Technology  Shenzhen P.
