Abstract

Inorganic non-metallic materials exhibit broad application prospects in tandem photovoltaic devices due to their excellent optoelectronic properties and thermal stability. However, issues such as interfacial defects, material degradation, and energy band mismatch still restrict their long-term stability and efficiency improvement. This paper systematically analyzes the functional positioning and performance of common inorganic non-metallic materials (e.g., oxides, nitrides, and chalcogenides) in tandem photovoltaic structures, and discusses their key roles in light absorption, carrier transport, and environmental protection. Focusing on material selection, interfacial engineering, and packaging technology, multiple strategies for enhancing stability are proposed, aiming to provide theoretical support and practical approaches for the design of high-efficiency and stable tandem photovoltaic devices.
