Photodetectors
as the core devices for optical signal conversion
need to balance high efficiency
fast response
and low-cost fabrication. Perovskite
with its advantages of high carrier mobility and tunable band gaps
have become an ideal alternative to silicon-based materials. This paper systematically reviews the progress in the patterned fabrication techniques and device construction of perovskite photodetectors across various dimensional material systems. First
it introduces five mainstream patterned fabrication methods for perovskites: template-confined growth
inkjet printing
vapor deposition
seed-induced growth
and conventional photolithography. Then
the latest research on image sensors based on perovskite materials in different dimensions is discussed. Following this
the paper highlights two promising application directions with great development potential: flexible wearable devices and electrochemical vision systems. Finally
the challenges and potential solutions for the future development of patterned perovskite photodetectors are presented to guide the development of high-performance perovskite optoelectronic devices.
