Silver nanowires (AgNWs) show great promise as transparent conducting electrodes in TPVDs due to their high conductivity, transparency, and environmentally friendly synthesis. Achieving high-performance optoelectronic devices requires careful optimization of material densities to balance light–matter interactions, which can be controlled by adjusting the density of AgNWs. This study examines the relationship between the AgNW density and key performance metrics of TPVDs featuring a pyroelectric-ZnO absorber. ZnO/NiO heterojunctions were fabricated via sputtering with varying densities of AgNWs applied as the top electrode. Among the densities tested, TPVDs with 35% AgNW coverage demonstrated the best on-site power performance, achieving a power conversion efficiency of 3.431% and an open-circuit voltage of 305 mV. Additionally, the study explored the effect of AgNW coverage on photodetection properties across the UV to the visible range. The optimized TPVD generated a pyrocurrent-assisted photocurrent of approximately 429 μA under modulated optical illumination, highlighting the impact of the top electrode design on photoelectric performance.

Solid polymer electrolytes (SPEs) have garnered increasing attention due to their nonvolatility, ease of processing, excellent mechanical properties, and stability. However, the performance of PEO-based solid-state batteries is often constrained by low ionic conductivity and poor mechanical strength. Therefore, we fabricated a nanofiber scaffold (PAN@UiO66) using electrospinning technology and then cast a solution containing zirconia (ZrO₂) fillers and bis(trifluoromethane)sulfonimide (LiTFSI), dispersed in poly(ethylene oxide) (PEO), onto the electrospun PAN@UiO66 scaffold to obtain a composite solid polymer electrolyte (CSPE, PZ/PAN@UiO66). The synergistic effect of the PAN@UiO66 scaffold and zirconia creates an amorphous-enriched region in the CSPE, providing uniform and abundant Lewis acid–base interaction sites, which reduce the crystallinity of the PEO-based solid electrolyte and enhance the diffusion and migration of lithium ions within the polymer. The components were physically characterized and electrochemically tested by using Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and energy-dispersive spectroscopy (EDS). The results indicate that the incorporation of PAN@UiO66 optimizes the lithium-ion transport behavior of PEO-based solid electrolytes and enhances their cycling stability. Specifically, at 60 °C, the lithium-ion transference number of the PAN@UiO66 nanofiber-enhanced composite solid polymer electrolyte (CSPE) increased from 0.20 to 0.40, the electrochemical voltage window expanded from 4.58 to 5.10 V, and the Li||Li symmetrical cell assembled with CSPE exhibited stable plating and stripping for over 670 h at a current density of 0.1 mA cm^–2.
