“…Ferroelectric 2D crystals are promising candidates for SMEC materials. [113,114] Ferroelectric materials can simultaneously harvest energy from the major environmental energy sources of heat, mechanical energy, and light. Ferroelectric materials have non-centrosymmetric crystal structures and permanent dipoles that allow them to operate as piezoelectric and pyroelectric materials and demonstrate M → E and T → E energy conversion, respectively (Figure 7).…”

Layered 2D crystals have unique properties and rich chemical and electronic diversity, with over 6000 2D crystals known and, in principle, millions of different stacked hybrid 2D crystals accessible. This diversity provides unique combinations of properties that can profoundly affect the future of energy conversion and harvesting devices. Notably, this includes catalysts, photovoltaics, superconductors, solar‐fuel generators, and piezoelectric devices that will receive broad commercial uptake in the near future. However, the unique properties of layered 2D crystals are not limited to individual applications and they can achieve exceptional performance in multiple energy conversion applications synchronously. This synchronous multisource energy conversion (SMEC) has yet to be fully realized but offers a real game‐changer in how devices will be produced and utilized in the future. This perspective highlights the energy interplay in materials and its impact on energy conversion, how SMEC devices can be realized, particularly through layered 2D crystals, and provides a vision of the future of effective environmental energy harvesting devices with layered 2D crystals.

“…Ferroelectrics (FE) are polar materials that exhibit spontaneously switchable electric polarization due to the noncoincidence of positive and negative charge centers. 14 Some excellent properties such as the piezoelectric effect and second-harmonic generation (SHG) effect [15][16][17] have been revealed. The ferromagnetism stems from the unpaired d electrons of the transition metal cations [18][19][20][21] and has attracted great attention in spintronics, 12 optoelectronics 22,23 and valleytronics.…”

Ferroelectricity, characterized by the reversible switching of spontaneous polarization (P s ) under external electric field, exists in polar crystalline materials without a spatial-inversion symmetry. On account of inherent P s , ferroelectric materials show intriguing physical properties including piezoelectricity, pyroelectricity, second-order optical nonlinearity, and electro-optic effect. Such functions of ferroelectric materials have been widely used for practical applications. Recently, hybrid perovskites are emerging as a promising ferroelectric family that enables the combination and/or coupling of ferroelectricity, photoexcitation, and semiconductor behaviors. Due to the polarization deterioration caused by leakage current of photoexcited carriers, however, it is still a challenge to accomplish practical applications of ferroelectric semiconductors in the photoelectric field. In this review, the recent progress of ferroelectric system of perovskite-type hybrids with different dimensions is summarized. Primarily, a brief description of crystallographic symmetry breaking which is a fundamental criterion to creating ferroelectricity, is illuminated. The combination and/or coupling of photoelectric properties with ferroelectric P s is then presented. Finally, the further development tendency and possible application outlooks of this ferroelectric material system are prospected.
