Due to their excellent properties, Zinc oxide nanowires (ZnO NW) have been attractive and considered as a promising electron-transporting layer (ETL) in flexible Perovskite Solar Cells (FPSCs). Since the first report on ZnO NWs-based FPSCs giving 2.6 % power conversion efficiency (in 2013), great improvements made, allowing reach up to∼15 nowadays. However, some issues still need be addressed, especially substrates, achieve uniform well-aligned NWs via low-cost chemical solution techniques. Several parameters, such growing method (time, temperature, precursors concentration), addition of seed (thickness, roughness, annealing temperature) substrate (rigid or flexible), play crucial role properties (i.e., length, diameter, density aspect ratio). In this review, these parameters control NWs, like growth techniques, utilization layers (time concentration) summarized. Then, particular focus NW's well use results development highlighted.

Abstract Physical unclonable functions (PUFs) have emerged as a promising encryption technology, utilizing intrinsic physical identifiers that offer enhanced security and tamper resistance. Multi‐level PUFs boost system complexity, thereby improving reliability fault tolerance. However, crosstalk‐free multi‐level remain persistent challenge. In this study, hierarchical PUF harnesses the spontaneous phase separation of silk fibroin /PVA blend random distribution silicon‐vacancy diamonds within is presented. The thermodynamic instability inherent unpredictability diamond dispersion gives rise to intricate patterns at two distinct scales, enabling time‐efficient authentication for cryptographic keys. These are complementary yet independent, inherently resistant replication damage thus affording robust proposed system. Furthermore, customized algorithms constructed: visual utilizes neural network combined structural similarity index measure, while spectral employs Hamming distance cross‐correlation bit operation. This attains high recognition rate without interscale crosstalk. Additionally, coding capacity exponentially using M‐ary encoding reinforce encryption. Hierarchical hold significant potential immediate application, offering unprecedented data protection key capabilities.
