Formamidinium lead iodide (α-FAPbI3) is an important part of highly efficient and stable organic-inorganic metal halide perovskites solar cells (PSCs). α-FAPbI3 has a unique change trend of optoelectronic properties during the phase transition. The heterophase is controlled in the films with the help of relative humidity (RH) and the relationship between them is analyzed. Aged under low humidity conditions, α-FAPbI3 transformed to PbI2, and the power conversion efficiency (PCE), absorption edges, absorption intensity and photoluminescence spectroscopy (PL) of the devices and films show a unimodal variation of increasing first and then decreasing. Aged at high humidity, α-FAPbI3 will shift to yellow-phase formamidinium lead iodide (δ-FAPbI3), and the above optoelectronic properties of the devices and films increase slightly and then decrease rapidly. By analysing the phenomenon, it was found that the material and structural changes during the phase transition of the films were the fundamental cause of the phenomenon. Based on this, the PCE of dry air aged devices accompanied by phase transition processes increases from 21.08% to 24.13% and then decreases to 19.88%. As the humidity increases, the increasing rate of optoelectronic properties in devices and films decreases, but the rate of decay increases. © 2024, The Authors. All rights reserved.

Fluoropolymers are fascinating in the high-tech industry due to their widespread applications, including fabricating actuators and sensors, controlling and monitoring storage, and energy generation. In this paper, we have communicated the development of an electroactive β-phase in flexible, lightweight, and thermally stable polymer nanocomposite in the configuration of 93% PVDF-7% NiFe2O4 by weight percentage fabricated via a cost-effective solution-casting technique. XRD, FTIR, and TGA were performed to check the structural and thermal stability of the system. Low loading of nano-nickel ferrite in the PVDF, the composite developed a substantial electroactive β-phase of 85.85% confirmed from FTIR analysis with enhanced thermal stability of 60.2 °C with respect to PVDF, as evident from the TGA study. FESEM, HRTEM, AFM, EDAX, and elemental mapping have been performed to study the microstructural and surface topology of the developed composite quantitatively and qualitatively. AFM study confirms the size of the spherulitics modulated to 7.4 μm as compared to 2.9 μm of PVDF referred to enhance thermal and mechanical stability along with increased β-phase. UV–visible spectroscopy study reveals the composite’s optical band gap to be 3.46 eV. The ambient condition’s capacitive, resistive, conductive, switching, and magnetic characteristics have been studied to exploit their properties for suitable device inclusion, including flexible electronics. The composite possesses a saturation polarisation of 1.5790 µC/cm2, remnant polarisation of 0.3725 µC/cm2, and a coercive field of 60.45 kV/cm at room temperature, which is useful for energy storage devices. The room-temperature ferrimagnetism suggests the composite’s application in multifunctional devices with a first-order magneto-electric (αME) coefficient of 11 mV/***.

There has been a disputation about how to achieve a pure mode I fracture mode and thus measure its toughness for an adhesively bonded bi-material DCB specimen. This paper therefore develops a theoretical methodology to calculate the tensile and shear stress distributions in the adhesive layer and to perform data reduction and mode partitioning for generic bi-material DCB specimens. The theoretical model is validated using experimental data. The adhesive layer in a generic bi-material DCB joint is loaded both in tensile and shear based on the predicted stress distributions in the adhesive layer, resulting in a mixed mode fracture behavior. The prediction results substantiate that a strain-based design principle eliminates the shear stresses and thus leads to pure mode I fracture in bi-material DCB specimens. This paper justifies that the established data reduction method is applicable for measuring mode I fracture toughness when a bi-material DCB is designed according to the strain-based design criterion. © 2024, The Authors.
