To advance off-grid energy solutions, developing flexible photobatteries capable of direct light charging is essential. This study presents an innovative photobattery architecture that incorporates zinc oxide (ZnO2) as electron-transporting and hole-blocking layer, combined with a hybrid methylammonium tin iodide composite poly-triarylamine (MASnI3/PTAA) for absorption hole transport. PTAA facilitates efficient transport to the anode, thereby enhancing charge separation reducing recombination losses. The MASnI3 perovskite serves effective sunlight absorber, generating carriers. ZnO2, known its high chemical stability rapid electron mobility, effectively blocks holes ensures swift flow cathode, which optimizes overall transfer dynamics. refined structure achieves photoconversion efficiency enhancement up 0.53% retains approximately 98% capacity after 700 cycles. optimized MASnI3/PTAA/ZnO2 demonstrates 3-fold reduction in time, positioning it strong candidate practical, light-rechargeable storage applications.

Abstract Aqueous zinc‐based batteries (AZBs) are gaining widespread attention owing to their intrinsic safety, relatively low electrode potential, and high theoretical capacity. Transition metal dichalcogenides (TMDs) have convenient 2D ion diffusion channels, so they been identified as promising host materials for AZBs, but face several key challenges such the narrow interlayer spacing lack of in‐deep understanding energy storage mechanisms. This review presents a comprehensive summary discussion structure, charge mechanisms, fabrication strategies TMD‐based cathodes AZBs. Firstly, structural features including phase types electrical properties TMDs underscored. Then, mechanisms activation principles in elaborated along with discussions about influence on electrochemical performance. Afterward, specific is focused high‐performance TMD cathodes, expansion, defect creation, transition, heteroatom doping. Finally, considered potential effective proposed design aqueous Zn‐TMDs batteries.

Abstract Directly harvesting solar power without traditional cells represents an efficient solution to the current energy challenges. Photo‐rechargeable batteries (PRBs) are receiving intense interest as they eliminate additional costs and losses associated with off‐grid generation. Herein, photo‐rechargeable aqueous Zinc‐ion (PRZIBs) constructed, using α‐MnO 2 nanowires bifunctional photoelectrodes reveal complex photo‐electrochemical effects in MnO PRZIBs. Through a series of situ characterizations under illumination, advantages intrinsic light based PRZIBs elucidated from three aspects: (1) inhibition Jahn‐Teller distortion via strengthened hydrogen bonding within , (2) suppression Mn 2+ dissolution through “protective layers” formed by photo‐promoted Zn /H + co‐intercalation, (3) acceleration desolvation electrolyte enabled abundant photogenerated holes. The demonstrate specific discharge capacity 308.1 mAh g −1 illumination (1 sun), along excellent cycling stability high conversion efficiency 0.68% (by photocharging only). In addition, interdigital micro‐PRZIBs successfully wearable sensors, demonstrating practical applicability. This work provides valuable insights into time‐resolved reaction mechanisms PRZIBs, opens new prospects for developing PRBs portable devices, i.e. smart textiles biosensors.
