“…also been reported, and they successfully mimicked various synaptic functions and promoted the development of photosynapse transistors [43,44]. However, these lead perovskites are toxic and harmful to the environment [50][51][52][53][54]. Compared with traditional lead perovskite materials, lead-free perovskite materials have low toxicity and broad application prospects, which have attracted people's attention [55][56][57][58][59].…”

Currently, neuromorphic computing is regarded as the most efficient way to solve the von Neumann bottleneck. Transistor-based devices have been considered suitable for emulating synaptic functions in neuromorphic computing due to their synergistic control capabilities on synaptic weight changes. Various low-dimensional inorganic materials such as silicon nanomembranes, carbon nanotubes, nanoscale metal oxides, and two-dimensional materials are employed to fabricate transistor-based synaptic devices. Although these transistor-based synaptic devices have progressed in terms of mimicking synaptic functions, their application in neuromorphic computing is still in its early stage. In this review, transistor-based synaptic devices are analyzed by categorizing them into different working mechanisms, and the device fabrication processes and synaptic properties are discussed. Future efforts that could be beneficial to the development of transistor-based synaptic devices in neuromorphic computing are proposed.

“…In addition to EoL strategies for lead recovery, encapsulation with effective lead capture is imperative for deploying lead-safe commercial perovskite modules. 62 Various effective approaches have been explored, including self-healing polymer-based encapsulation 63 and the integration of lead-absorbing chemical agents. The integration of cation exchange resins (CERs), as demonstrated by Chen et al , has successfully reduced lead leakage to 7 ppb, below the safe level (15 ppb) of drinking water according to the US Federal 40 CFR 141 regulation.…”
