Metal halide perovskites have become well-deserved “star” materials among a variety of semiconductors owing to their excellent optoelectronics properties, such as high photoluminescence (PL) quantum yield (QY), high absorption coefficient, tunable bandgaps, long carrier diffusion lengths, and high defect tolerance, attracting enormous attention from both academia and industry. Meanwhile, DLW, based on the interaction between light and matter, is an efficient, contactless, mask free, and depth-resolved micro-patterning technique. It is typically performed by coupling a laser beam with a high-resolution microscope to minimize the output focal spot. The…
