  In this study, we present a complex investigation for miniaturizing of
perovskite photodiodes (PPDs) in various geometries with use of ultraviolet
laser scribing (UV-LS). Employing a 355 nm (3.5 eV) pulsed laser at 30 kHz, we
successfully manufactured PPDs with pixel configurations of 70x130 um2, 520x580
um2, and 2000x2000 um2. The utilization of UV-LS has a proven efficiency in
achieving relevant diode characteristics, such as low dark currents and high
shunt resistance, as well as ultrafast response. The multi-step scribing cycle
provided precise patterning of perovskite photodiodes (PPDs) in a string
design. The dark current densities demonstrated exceptional uniformity, ranging
from 10-10 A/cm2 for 2000x2000 um2 pixelated PPDs to 10-9 A/cm2 for the 70x130
um2 configuration. The string PPDs, consisting of 10 pixels per string,
displayed homogenous dark current values, ensuring effective isolation between
devices. Under green light illumination (540 nm), all PPD types exhibited a
broad Linear Dynamic Range (LDR). Specifically, LDR values reached 110 dB, 117
dB, and 136 dB for 70x130, 520x580, and 2000x2000 devices, respectively,
spanning an illumination intensity range from 2*10-3 mW/cm2 to 2 mW/cm2. High
responsivity values up to 0.38 A/W, depending on the PPDs geometry, highlight
the potential of laser scribing devices for sensing in the visible range. The
calculated specific detectivity performance (from 1011 to 1013 Jones) surpasses
commercial analogs, while the sub-microsecond response of 70x130 um2 and
520x580 um2 miniaturized devices underscores their suitability for precise time
resolution detection systems.
