“…[11][12][13][14] WO 3 , as an important wide bandgap semiconductor material, has been widely explored in gas sensors, smart windows, electrochromic devices, photocatalysis, and UV PDs, whereas further applications in flexible electronics have been rarely reported due to its brittleness. [15][16][17] The WO 3 is brittle in its bulk form, however, this issue can be well resolved by the thin films of WO 3 for the applications of flexible photo-detectors. It is possible to deposit WO 3 as a thin film through different deposition techniques.…”

The emerging flexible device technologies have fascinated the modern optoelectronic industry owing to their invincible properties such as wearable, stretchable, smart, energy‐efficient, scalability, cost‐effective, and high performance. However, there is still room for improvements such as performance, reliability, and mass production. This research work fabricates laser‐induced graphene (LIG) interdigitated electrodes based on flexible UV photodetectors over polyimide substrate, using solution‐processed tungsten oxide (WO3) thin film as photoactive material. The best device performance is achieved through the optimization of laser power for the deposition of LIG, as well as a different solvent for WO3. The device shows excellent photoresponsivity, external quantum efficiency, and specific detectivity of 500 mA W−1, 164%, and 3.09 × 1012 Jones, respectively. Moreover, a fast response time, such as 0.3 ms for 375 nm light, is observed. This study offers a comprehensive elucidation of the intricate process through which photoelectrons are moved toward WO3 facilitated by the electric field present at the interface of the LIG and WO3.

The application of vanadium redox flow batteries (VRFBs) has encountered challenges because the most commonly used commercial membrane (perfluorinated sulfonic acid, PFSA) has severe vanadium ion permeation, which yields poor stability of the battery. Herein, a PFSA‐based hybrid membrane with a sandwich structure created using a reinforced polytetrafluoroethylene thin layer with hydrophilic nanohybrid fillers is developed. The tungsten trioxide (WO3) nanoparticles are in situ grown on the surface of graphene oxide (GO) nanosheets to overcome the electrostatic effect, and to enhance the hydrophilicity and dispersibility of GO nanosheets, which is embedded in the PFSA matrix to act as a “barrier” to reduce vanadium ions permeation. In addition, these hydrophilic WO3 nanoparticles on GO nanosheets surface serve as proton active sites to facilitate proton transportation. As a result, at 120 cm−2, the cell of the hybrid membrane displays high Coulombic efficiency (over 98.1%) and high energy efficiency (up to 88.9%), better than the commercial Nafion 212 membrane at the same condition. These performances indicate the proposed hybrid membrane is applicable for VRFB application. Also, this design method of the membrane can be extended to other fields including water treatments and fuel cells.
