Overview
Observational analysis reveals performance degradation in tandem solar cells under thermal cycling, suggesting advancements for real-world applications.
Key Points
Performance degradation occurs rapidly, with a 60% relative loss in power conversion efficiency during the burn-in phase.
Temperature change rate of 10 °C per minute induces strain and phase transformations, affecting solar cell stability.
Operando grazing-incidence wide-angle X-ray scattering and photoluminescence measure degradation mechanisms in real-time.
Understanding these degradation mechanisms may enable improvements in operational thermal stability for solar cells.
