Perovskite single-crystal arrays have attracted intensive attention because of their great potentials for integrated optoelectronic ***,the traditional top-down lithography strategy requires complex processing and is detrimental to perovskite crystal structures,which is incompatible to directly pattern perovskite single ***,we report a lithography-free method to realize the controllable growth of perovskite single-crystal *** introducing a printed hydrophilic-hydrophobic substrate into the crystallization system,the MAPbCl_(3) single-crystal arrays with precise location and uniform size are effectively *** method can be applied to prepare diverse perovskite single-crystal arrays,including MAPbBr_(3),CsPbCl_(3),CsPbBr_(3),Cs_(3)Cu_(2)I_(5),Cs_(3)Bi_(2)I_(9),and(BA)_(2)(MA)_(3)Pb_(4)I_(11).The perovskite single crystals can be selectively grown on the electrodes to fabricate ultraviolet *** strategy demonstrates a facile approach to fabricate large-scale perovskite single-crystal arrays and opens a pathway to produce diverse perovskite optoelectronic devices.

关键词： single-crystal arrays lithography-free hydrophilic-hydrophobic substrate ultraviolet(UV)photodetector
