Abstract: ABSTRACT OPTICAL-SPECTRAL AND ELECTRICAL IMPEDANCE MONITORING OF TANDEM SOLAR CELL DEGRADATION This invention introduces a high-precision, self-contained structural health monitoring system designed to continuously evaluate the operational integrity of Perovskite-on-Silicon tandem solar cells using a dual-method approach. The system integrates both an interlayer optical-spectral sensing unit and an electrical impedance diagnostic unit operating on real- time signal processing, enabling reliable fault detection even in the absence of visible power drops. The diagnostic process is enhanced with fluorescent-d~ped fiber optic transducers and preceded by an Edge-A! processing stage that filters electromagnetic interference and environmental noise, thereby improving accuracy and ensuring reliability in the monitored data. A spatial localization module maintains the tracking of internal micro-cracks in a stable, highresolution map regardless of turbulent electrical conditions, ensuring consistent structural health assessment during operation. A threshold-based activation system, governed by a multi-node spectral logic controller, initiates maintenance alerts only when internal degradation exceeds a specified depth. Additionally, an automated fault localization system identifies specific rupture coordinates from the cell laminate using internal spectral shifts without interrupting power flow.
