Halide perovskite solar cells (PSCs) have rapidly approached the efficiency levels of traditional silicon photovoltaics, marking a significant breakthrough in solar technology. However, their commercial viability is compromised by their limited long-term stability. This presentation focuses on the recent strides made in enhancing the stability of PSCs through innovative interface engineering. By examining the primary factors influencing PSC stability and the mechanisms of device degradation, we have explorde how interface manipulation serves both as a corrective measure for surface defects and a defensive mechanism against environmental degradation. Special emphasis will be placed on the latest advancements in interface modification agents, interfacial regulation strategies, and the design of novel charge transport and capping layers. We aim to provide a comprehensive overview of the current challenges, recent technological advances, and future directions in the sustainability of halide perovskite photovoltaics, emphasizing the pivotal role of interface engineering in the evolution of this promising technology.
