Summary: In this work, self-powered n-Zinc Oxide/p-Poly(3-hexylthiophene) (n-ZnO/p- P3HT) inorganic-organic hybrid heterojunction photodetectors were successfully fabricated. The polymer P3HT can efficiently respond to visible light, while the n-ZnO layer functions as a light scattering and electron transport layer. By incorporating 1D-ZnO nanorod arrays (NRAs) and 0D-ZnO quantum dots (QDs) hybridization structure, the performance of the photodetector was greatly improved. The present work provides a new way to optimize the performance of polymer photodetectors.

Summary: Anode-free lithium metal batteries (AFLMBs) have the potential to enhance the energy density of lithium-ion batteries by eliminating the need for conventional graphite anodes. However, AFLMBs face challenges such as inferior stability of the solid electrolyte interphase (SEI) layer and inhomogeneous lithium deposition. By coating the copper current collector with carbonized polydopamine (CPD), highly efficient and reversible lithium plating and stripping processes can be achieved, leading to improved cycling stability. The anode-free full cell, composed of CPD-coated copper current collector and LiFePO4 cathode, demonstrates significantly enhanced electrochemical performance.
