By applying the outward uniform strain on the non-centrosymmetric piezoelectric semiconductor, the polarization charges on the material surface are induced. Polarization charges are often generated within the crystals provided that the applied strain is non-uniform. The strain applied has an effect on electronic transport and can be utilized to modulate the properties of the material. The effect of multiway coupling between piezoelectricity, semiconductor transport properties, and photoexcitation results in piezo-phototronic effects. Recent studies have shown the piezoelectric and semiconductor properties of third-generation semiconductors have been used in photodetectors, LEDs, and nanogenerators. The third-generation piezoelectric semiconductor can be used in high-performance photovoltaic cells. A third-generation piezo-phototronic solar cell material is theoretically explored in this manuscript on the basis of a GaN metal-semiconductor interaction. This study aims to determine the effects of piezoelectric polarization on the electrical performance characteristics of this solar cell material. Performance parameters such as Power Conversion Efficiency, Fill Factors, I-V Characteristics, Open Circuit Voltage, and Maximum Output Power have been evaluated. The piezophototronic effect can enhance the open-circuit current voltage by 5.5 percent with an externally applied strain by 0.9 percent. The study will open a new window for the next generation of high-performance piezo-phototronic effects.

Flexible two-dimensional (2D) piezoelectric materials are promising for applications in wearable electromechanical nano-devices such as sensors, energy harvesters, and actuators. A large piezoresponse is required for any practical applications. Based on first-principles calculations, we report that ferroelectric TiOX2 as well as multiferroelectric VOX2 (X = F, Cl, Br) monolayers exhibit significantly large in-plane stress (e11) and strain (d11) piezoelectric coefficients. For example, in-plane piezo-response of TiOBr2 (both e11 and d11) is about an order of magnitude larger than that of widely studied 1H-MoS2 monolayer, and also quite comparable to giant piezoelectricity of group-IV monochalcogenide monolayers e.g., SnS. Moreover, d11 of MOX2 monolayers - ranging from 29.028 pm/V to 37.758 pm/V - are significantly higher than the d11 or d33 of commonly used 3D piezoelectrics such as w-AlN (d33 = 5.6 pm/V) and α-quartz (d11 = 2.27 pm/V). Such large d11 of MOX2 monolayers originates from low in-plane elastic constants with large e11due to large Born effective charges (Zij ) and atomic sensitivity ( du/dη ) to an applied strain. We also show the possibility of opening a new way of controlling piezoelectricity by magnetic field.
