However, established patterning techniques meet their limitations when it comes to hybrid perovskite single crystals with multilayered diode structures. In this work, an Ostwald ripening assisted photolithography (ORAP) patterning process, which employs wettability-assisted blade-coating and Ostwald ripening assisted crystallization, is developed for fabricating patterned perovskite single-crystal microarrays. Optoelectronic devices based on uniform perovskite single-crystal microarrays with a multilayered diode structure can be constructed through the ORAP process. To demonstrate the compatibility of the ORAP process with the manufacture of optoelectronic devices, patterned CH3NH3­PbBr3 single-crystal microarray solar cells, which show enhanced performance than solar cells based on CH3NH3­PbBr3 continuous single crystals reported, were fabricated. With the development of perovskite research, we are confident that the ORAP process opens a new avenue to fabricate optoelectronic devices based on perovskite microarrays. ER -
