Laser assisted rapid fabrication of perovskite photodetector

摘要: In the past few years, with advance of laser technology, engraving has been considered as an alternative method to traditional lithography in fabrication microfluidic devices. Considering solution-based main technique for perovskite deposition, capillary motion precursor can be employed filling a laser-engraved patterned conducting layer. Herein, we used CO2 micromachining photodetector. First, several microchannels were formed by indium tin oxide (ITO) coated polyethylene terephthalate (PET) substrates. Power, speed and frequency parameters varied order achieve desired channel roughness. The samples characterized scanning electron microscope (SEM) potentiostat. I-V characteristics bode plots sample showed capacitive inductive behavior. Finally, simulation tool was analyze experimental data. This approach offers simple, rapid low-cost photodetector large-scale commercial application.
