Tunable Periodic Nanopillar Array for MAPbI₃ Perovskite Photodetectors with Improved Light Absorption.

ABSTRACT: In the field of optoelectronic applications, the vigorous development of organic-inorganic hybrid perovskite materials, such as methylammonium lead triiodide (MAPbI₃), has spurred continuous research on methods to enhance the photodetection performance. Periodic nanoarrays can effectively improve the light absorption of perovskite thin films. However, there are still challenges in fabricating tunable periodic patterned and large-area perovskite nanoarrays. In this study, we present a cost-effective and facile approach utilizing nanosphere lithography and dry etching techniques to create a large-area Si nanopillar array, which is employed for patterning MAPbI₃ thin films. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) results reveal that the introdu
