Study Application 1.
● High resolution laser scanning confocal image
● For studying perovskite solar cell grain-boundary structures and surface morphology
● Grain size of perovskite solar cell is a key factor of solar conversion efficiency. Utilize laser scanning confocal microscope, we would be able to investigate the grain size even if the solar cell is made into device.
● A high resolution 1024x1024 image can be acquired less than 5 second.
● Meanwhile, if sample have regional distributions, users can use ROI to investigate different areas without any sample moving.

Study Application 2.
● Study in micro-scale perovskite grain boundary defects
● Defects in perovskite solar cell will be reflected on PL characteristics. Utilizing PFCM-1000, we can not only see the grain boundary distribution by its PL intensity, but also detect PL spectrum by setting ROI for micro-scale spot less than 1µm, which could be indications for defect structure to improving the manufacture.
Study Application 3.
● FLIM(Fluorescence lifetime imaging microscope)
● By synchronizing TCSPC system with laser scanning confocal microscope, we are able to measure 2D optics intensity distribution and PL decay time of in the same time. As images showed below, we can clearly understand that higher intensity of local area is contributed by longer PL decay time.
● FLIM is total investigation for our enclosed device.
