Thanks to attractive properties, such as defect tolerance, broad bandgap tunability, high quantum yields, andlarge absorption coefficient, perovskites have emerged as a star material in the past decade. Meanwhile, optical nano/microstructures made of perovskites offer a facile and efficient strategy to improve light-harvesting performance and sensitivity of polarization. However, there is no low-cost, high-accuracy, and reproducibility technique for large-scale fabrication of perovskite nano/microstructures. Here, femtosecond laser direct writi...
