“…The halide materials show great promise for decreasing the grid parity taking advantages of low-cost starting materials ( Kim et al., 2012 , 2020 ; Lee et al., 2019 ; Seo et al., 2019 ), high throughput ( Brenner et al., 2016 ), and low-temperature fabrication techniques compared with the traditional monocrystalline Si and III-V PV devices ( Brenner et al., 2016 ; Ding et al., 2020a ; Kim et al., 2017 ; Lee et al., 2019 ; Seo et al., 2019 ). Not only the PV devices but also the superior optoelectronic properties of the halide perovskites enable application of the materials in a variety of devices including photodetectors ( Chun et al., 2018 ; Saidaminov et al., 2015 ), light emitting diodes( Lee et al., 2017 , 2020 ), transistors ( Senanayak et al., 2017 ), memories ( Kim et al., 2019 ; Yang et al., 2018 ), nanogenerators ( Ding et al., 2020b ), and spintronics ( Wang et al., 2019 ).…”

Unique organic-inorganic hybrid semiconducting materials have made a remarkable breakthrough in new class of photovoltaics (PVs). Organic-inorganic metal (Pb and/or Sn) halides (-I, -Br, and -Cl) are the semiconducting absorber with the crystal structure of the famous ''Perovskite''. It is widely called ''perovskite solar cells (PSCs)'' in PV society. Now, the power conversion efficiency (PCE) of PSCs is recorded in 25.5%. Prototypical composition of the absorbers is (A = methylammonium [MA], formamidinium [FA], and Cs), (M = Pb and/or Sn), and (X = I, Br, and Cl) in the form of perovskite AMX 3 . Since the report on the stable all solid-state PSCs in 2012, the average annual growth rate of PCE is well over $10%. Such an outstanding PV performance attracts huge number of scientists in our research society. Their chemical as well as physical properties are dramatically different from monocrystalline Si, GaAs, other III-IV semiconductors, and many oxides with the crystal structure of perovskite. In this review, different fundamental aspects, in particular, the dynamic properties of A site cationic molecules and PbI 6 octahedrons linked with their corners, from other semiconducting and dielectric materials are reviewed and summarized. Upon discussing unique properties, perspectives on the promising PV applications based on the comprehension in dynamic nature of the orientation in A site molecule and PbI 6 octahedron tilting will be given.

Triboelectric nanogenerators (TENGs) that utilize triboelectrification and electrostatic induction to convert mechanical energy to electricity have attracted increasing interest in the last 10 years. As a universal physical phenomenon, triboelectrification can occur between any two surfaces that experience physical contact and separation regardless of the type of material. For this reason, many materials, including both organic and inorganic materials, have been studied in TENGs with different purposes. Although organic polymers are mainly used as triboelectric materials in TENGs, the application of inorganic nanomaterials has also been intensively studied because of their unique dielectric, electric, piezoelectric, and optical properties, which can improve the performance of TENGs. A review of how inorganic nanomaterials are used in TENGs would help researchers gain an overview of the progress in this area. Here, we present a review to summarize how inorganic nanomaterials are utilized in TENGs based on the roles, types, and characteristics of the nanomaterials.

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.
