A method for preparing perovskite single-crystal microwire arrays by a melting method

This invention provides a method for preparing perovskite single-crystal micron-shaped wire arrays using a melt method. Perovskite powder is added to the gap between a silicon pillar template and a quartz substrate, forming a sandwich structure. This sandwich structure is placed on a heating device, and the temperature is increased. When the temperature exceeds the melting point of perovskite, the melt flows along the top of the silicon pillar until it covers the entire silicon pillar template. The temperature is then slowly lowered until it falls below the solidification point of perovskite, resulting in a regularly arranged perovskite micron-shaped wire array on the substrate. Compared to traditional liquid-phase methods for preparing perovskite arrays, this invention ensures crystal quality, avoids the harm to health and the environment caused by organic solvents, and enables the array preparation of perovskite that is insoluble in organic solvents. Furthermore, it provides a new approach for the array preparation of other perovskites and their application in optoelectronic devices.
