Facile Fabrication of Highly Crystallized, Air‐Stable, and Flexible Perovskite Micromesh Film Photodetector
Perovskite materials such as organic‐inorganic MAPbX3 (X = Cl, I, Br) have attracted broad interests in photoelectric applications, such as image sensors and photovoltaics.

| description | Perovskite materials such as organic‐inorganic MAPbX3 (X = Cl, I, Br) have attracted broad interests in photoelectric applications, such as image sensors and photovoltaics. Here, a facile and general approach, called soft‐print solvent‐assisted evaporation crystallization (SSEC) is reported, for fabrication of highly crystallized, air‐stable, and flexible perovskite micromesh films, including organic–inorganic (MAPbX3) and inorganic (CsPbX3) perovskite. Scanning and transmission electron microscopy (SEM/TEM) characterization reveals their high crystallinity without obvious grain boundaries. The photodetectors constructed based on MAPbI3 micromesh films exhibit a typical responsivity of ≈352 A W−1 and detectivity of ≈5.7 × 1013 Jones (at 650 nm in wavelength). The MAPbI3 micromesh film also shows good mechanical stability when bended at different bending radius, and after 800 bending cycles, they still exhibit highly reproducible photocurrent and on/off switching ratios. Furthermore, they are also air‐stable that they can survive for >20 days in high humid environments (65–75%) with |

Highly crystallized organic‐inorganic/inorganic perovskite micromesh films are prepared using a facile and general soft‐print solvent‐assisted evaporation crystallization approach without obvious grain boundaries. The perovskite micromesh films have tunable composition (both MAPbX3 and CsPbX3), pore width, period, and porosity. The MAPbI3 micromesh film also shows excellent photoelectric performance, mechanical flexibilities, and humidity resistance, which indicates their great potential in high‐performance flexible device applications.</description><identifier>ISSN: 2195-1071</identifier><identifier>EISSN: 2195-1071</identifier><identifier>DOI: 10.1002/adom.202401287</identifier><language>eng</language><publisher>Weinheim: Wiley Subscription Services, Inc</publisher><subject>Bend radius ; Crystallization ; Cycle ratio ; flexible device ; Grain boundaries ; MAPbI3 ; micromesh film ; Optoelectronics ; organic–inorganic perovskite ; Perovskites ; photodetector ; Photoelectric effect ; Photoelectric emission ; Photoelectricity ; Photometers ; Photovoltaic cells</subject><ispartof>Advanced optical materials, 2024-12, Vol.12 (34), p.n/a</ispartof><rights>2024 Wiley‐VCH GmbH</rights><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c2027-25b530ad1f15472cf3345a0c293b610795750310149f2340c79d1853bdf0ded63</cites><orcidid>0000-0002-3479-0130</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fadom.202401287$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fadom.202401287$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,776,780,1411,27901,27902,45550,45551</link.rule.ids></links><search><creatorcontrib>Xiong, Yuting</creatorcontrib><creatorcontrib>Chen, Bo</creatorcontrib><creatorcontrib>Xu, Xiuzhen</creatorcontrib><creatorcontrib>Dai, Shijie</creatorcontrib><creatorcontrib>Zhan, Yiqiang</creatorcontrib><creatorcontrib>Xu, Xiaobin</creatorcontrib><title>Facile Fabrication of Highly Crystallized, Air‐Stable, and Flexible Perovskite Micromesh Film Photodetector</title><title>Advanced optical materials</title><description>Perovskite materials such as organic‐inorganic MAPbX3 (X = Cl, I, Br) have attracted broad interests in photoelectric applications, such as image sensors and photovoltaics.
