Ultrafast laser-assisted perovskite-based optoelectronic devices

Perovskite materials have attracted widely interest in the study of their physical mechanisms and applications due to variable special structures, a wide variety of organic-inorganic compounds, and excellent photoelectric properties such as high carrier mobility and high quantum luminescence efficiency. Ultrafast laser with the characteristics of ultrafast and ultrastrong has been another research hotspot in recent years. Ultrafast laser processing mainly relies on cold processing, and the perovskite devices prepared by this method have the characteristics of small heat affected zone, superior performance, and good stability. In this paper, the latest studies in the processing of perovskite materials by ultrafast laser are reviewed, divided into two parts: (i) the interaction of ultrafast laser with perovskite materials and the changes of perovskite physical properties irradiated by ultrafast laser; (ii) the ultrafast laser-assisted perovskite-based devices for luminescence, storing optical information, converting optical signals, optical imaging. Finally, the development, application and industrialization of perovskite materials in the field of optoelectronics are prospected.
