“…This phenomenon is called an orientation effect of non-uniformly spaced aggregates of nanostructured substance [53]. A lower electrical resistance in a compressive or tensile state than that in a neutral state is also observed for the given ITO thin films under cyclic bending in our previous study [41].…”

“…However, it is necessary to study the concurrent change of electrical conductivity of ITO thin film under long-term mechanical bending, and its correlation with the mechanical failure mechanism. In our prior work [41], the effect of cyclic bending on the in situ variation of electrical conductance of ITO thin film has been investigated. In this study, changes of electrical conductance in ITO thin film on different polymer substrates are investigated by conducting long-term static bending tests with various radii of curvature.…”

The objective of this study is to investigate the effect of long-term static bending on the conductive characteristics of indium tin oxide (ITO) thin film in flexible optoelectronics. Two types of substrate are considered, namely ITO on polyethylene naphthalate (ITO/PEN) and ITO on polyethylene terephthalate (ITO/PET). Electrical properties of the ITO/PEN and ITO/PET sheets are measured in situ under static bending at various radii of curvature. Experimental results indicate that no significant change in electrical resistance of the ITO/PEN and ITO/PET sheets is found for compressive bending after 1000 h at a curvature radius of 10 mm or larger. However, the ITO/PEN and ITO/PET sheets are seriously damaged under a tensile bending of 10 mm radius and 5 mm radius, respectively. The given ITO/PET sheet exhibits a greater resistance to long-term mechanical bending than the ITO/PEN one, which is attributed to the effect of stiffness and thickness of substrate. As the given PET substrate has a lower stiffness and thickness than the PEN one, ITO thin film in the ITO/PET sheet has a smaller stress given a bending radius. Consequently, a smaller extent of change in the electrical conductance of ITO thin film is found in the ITO/PET sheet.

“…This indicated the remarkable decrease of conductivity of the ITO-based conductive RCF due to the bending treatment. As the inorganic conductive layer, the ITO was characterized by high rigidity, friableness, and low flexibility (Lee et al 2014;Tran et al 2015). The ITO layer was fractured by the bending treatment, thus disturbing the current carrier mobility.…”

Regenerated cellulose film (RCF) has potential as a conductive substrate due to features such as its degradability, transparency, and flexibility. Indium doped tin oxide (ITO) is a conventional conductive material, but its rigidity restricts the formation of flexible conductive film. In this study, silver nanowires (AgNWs) were introduced between the RCF and the ITO conductive framework. Additionally, the fabrication of flexible, conductive, and transparent RCF was conducted. The AgNWs-ITO based RCF demonstrated high conductivity (170 Ω per sq) and transparency (78%) by the addition of 50 μL of AgNWs. After bending the sample 50 times with a 5 mm curve radius, the as-prepared conductive RCF presented an electric resistance improvement of 19%, with a 485% increase for the control ITO-based RCF. This is a result of the AgNWs framework, which can lessen the destruction of the bending treatment on the conductive layer and can also desirably connect the ITO conductive sections. The novel approach can expedite the versatile applications of flexibly conductive RCF on printable, portable, and wearable electronic devices.

“…It has excellent optical and electrical properties, but its mechanical properties are poor for flexible applications. The mechanical degradation behavior of ITO is buckling delamination [14,15]. Preliminary SEM images of ITO on PET after bending or folding the material demonstrate parallel cracks with moderately uniform and periodic spacing [16].…”

Flexible perovskite solar cells introduce opportunities for high throughput, high specific weight, and short energy payback time photovoltaics. However, they require additional investigation into their mechanical resiliency. This work investigates the mechanical properties and behaviors of perovskite thin films and builds a robust model for future research. A two-pronged approach was utilized. Perovskite thin films were flexed in a three-point bend mode with in-situ SEM. Novel insights into the perovskite mechanical behaviors with varying substrate layers were gained. Modeling and validation, the second prong, was completed with finite element analysis. Model coupons of the imaged perovskite architectures were built, with sensitivity analysis completed to provide mechanical property estimates. The results demonstrate that mechanical degradation of perovskite thin films on polyethylene terephthalate (PET) primarily presents as a crack in the grain boundaries between crystals. Perovskite thin films on Indium Tin Oxide (ITO) and PET primarily crack in a periodic pattern regardless of the placement of perovskite crystals.
