Abstract Tandem solar cells combining perovskite and silicon have witnessed rapid development in recent years. However, the top cell, utilizing wide‐bandgap as absorbers generally suffer significant open‐circuit voltage ( V OC ) deficit, particularly for inorganic perovskite, which poses a considerable obstacle to enhancing power conversion efficiency (PCE).

Moving object detection (MOD) plays an important role in many applications that aim to identify regions of interest videos. However, most existing MOD methods ignore the variability brought by time-varying information. Additionally, network frameworks primarily focus on low-level feature learning, neglecting higher-level contextual understanding required for accurate detection. To solve above issues, we propose a symmetric Dynamic-Aware Network (DAN) MOD. DAN explores interactions between...
