Abstract

Facing the industrial demands of the “Dual Carbon” strategy and the development of a new generation of optoelectronic energy storage devices, all-solid-state lithium batteries (ASSLBs) and perovskite solar cells (PSCs) have emerged as international research frontiers in the field of advanced new energy materials and devices. Excessively high interfacial impedance, severe non-radiative recombination of defects, insuffi cient lattice stability, and poor consistency in large-scale fabrication are the common scientifi c bottlenecks restricting the performance breakthrough of these two types of devices. Based on the fundamental theories of materials physics, this paper systematically elucidates the ion transport mechanisms of solid-state electrolytes and the dynamic laws of photogenerated carriers in perovskites. Focusing on the key scientific issues including solid-solid interfacial charge transport, interfacial barrier modulation, defect passivation, and lattice stabilization, we review the cutting-edge regulation strategies such as element doping, interfacial modifi cation, in-situ composite fabrication, and the construction of low-dimensional heterostructures. Combined with the industrial practices of Wuhan East Lake High-tech Development Zone (Optics Valley) in the fi elds of solid-state batteries, perovskite photovoltaics, sodium-ion energy storage, and interfacial regulation equipment, we analyze in depth the technical pathways and practical bottlenecks for the transformation of frontier materials from laboratory research to industrialization. The research results indicate that atomic-level precise interfacial regulation, multi-scale defect engineering, and the integrated fabrication of optoelectronic energy storage devices are the core directions for the future performance breakthrough of such devices. This work can provide theoretical references and research ideas for the study of interfacial physics of new energy materials, the design of high-performance devices, and regional industrial technological innovation in the new energy fi eld.
