“…Furthermore, Nie et al demonstrated a piezophototronic effect enhanced PD array based on polycrystalline perovskite. [ 55 ] Compared with single‐crystal perovskite, polycrystalline perovskite materials are easier to prepare, lower environmental requirements, and higher conversion efficiency. Through systematic experiments, they studied the effects of excitation light, bias voltage, and different strain on the efficiency of polycrystalline perovskite PDs.…”

The piezophototronic effect is the coupling of piezoelectricity, semiconductor behavior and photon excitation in wurtzite materials, which can enhance the performance of optoelectronic nano‐devices by regulating a series of processes of carrier injection, transport, and recombination. In recent years, many research results have been reported on the improvement of nanophotoelectric nano‐device efficiency by piezophototronic effect, such as photovoltaic devices, light‐emitting devices, transistors, etc. Herein, the research results of piezophototronic effect in the field of nanosensors, including enhancing the performance of traditional nanosensors and new types of pressure/deformation/tactile sensors based on piezophototronic effect are comprehensively summarized. Finally, the future development of piezophototronic effect in the field of nanosensors is discussed.

“…Ferroelectric EA 4 Pb 3 Br 10 SCFs as one kind of piezoelectric materials are expected to possess an effective piezoelectric coefficient, which may play a vital role in the piezoelectric device. [ 18–23 ] Figure 3c shows the lateral piezoresponse as a function of the driving voltage, which is correlated with the contact resonant frequency at the range of 240–260 kHz.

“…Note that EA 4 Pb 3 Br 10 SCF‐based photodetectors are endowed with spontaneous piezoelectric polarization that enables to modulate the separation and transportation of the photogenerated carriers induced by piezo‐phototronic effect.

“…In recent years, piezo‐phototronic effect coined by Wang has been extensively exploited in the third‐generation semiconductors and transition‐metal dichalcogenides, such as ZnO, GaN, and MoS 2 . [ 18–23 ] The three‐way coupling among piezoelectricity, photoexcitation, and semiconductor characteristics in these materials gives rise to an effective enhancement of optoelectronic device performance. Strain‐induced piezoelectric charges and piezopotential at the contact interface may act as a “gate” role to tailor carrier separation and transport during the optoelectronic processes, which is the working principle of the piezo‐phototronic effect.…”

“…Typical 3D CH 3 NH 3 PbI 3 (MAPbI 3 ) perovskites have been attempted in various piezo‐phototronic devices, however, the output performance and modulation by piezo‐phototronic effect remain modest, which can be ascribed to their poor ferroelectric and piezoelectric performance. [ 21–23 ]…”

2D hybrid perovskites are very attractive for optoelectronic applications because of their numerous exceptional properties. The emerging 2D perovskite ferroelectrics, in which are the coupling of spontaneous polarization and piezoelectric effects, as well as photoexcitation and semiconductor behaviors, have great appeal in the field of piezo‐phototronics that enable to effectively improve the performance of optoelectronic devices via modulating the electro‐optical processes. However, current studies on 2D perovskite ferroelectrics focus on bulk ceramics that cannot endure irregular mechanical deformation and limit their application in flexible optoelectronics and piezo‐phototronics. Herein, we synthesize ferroelectric EA4Pb3Br10 single‐crystalline thin‐films (SCFs) for integration into flexible photodetectors. The in‐plane multiaxial ferroelectricity is evident within the EA4Pb3Br10 SCFs through systematic characterizations. Flexible photodetectors based on EA4Pb3Br10 SCFs are achieved with an impressive photodetection performance. More importantly, optoelectronic EA4Pb3Br10 SCFs incorporated with in‐plane ferroelectric polarization and effective piezoelectric coefficient show great promise for the observation of piezo‐phototronic effect, which is capable of greatly enhancing the photodetector performance. Under external strains, the responsivity of the flexible photodetectors can be modulated by piezo‐phototronic effect with a remarkable enhancement up to 284%. Our findings shed light on the piezo‐phototronic devices and offer a promising avenue to broaden functionalities of hybrid perovskite ferroelectrics.

Contact engineering is a prerequisite for achieving desirable functionality and performance of semiconductor electronics, which is particularly critical for organic–inorganic hybrid halide perovskites due to their ionic nature and highly reactive interfaces. Although the interfaces between perovskites and charge‐transporting layers have attracted lots of attention due to the photovoltaic and light‐emitting diode applications, achieving reliable perovskite/electrode contacts for electronic devices, such as transistors and memories, remains as a bottleneck. Herein, a critical review on the elusive nature of perovskite/electrode interfaces with a focus on the interfacial electrochemistry effects is presented. The basic guidelines of electrode selection are given for establishing non‐polarized interfaces and optimal energy level alignment for perovskite materials. Furthermore, state‐of‐the‐art strategies on interface‐related electrode engineering are reviewed and discussed, which aim at achieving ohmic transport and eliminating hysteresis in perovskite devices. The role and multiple functionalities of self‐assembled monolayers that offer a unique approach toward improving perovskite/electrode contacts are also discussed. The insights on electrode engineering pave the way to advancing stable and reliable perovskite devices in diverse electronic applications.
