A hurdle in commercializing the perovskite/Si tandem solar cell: Potential-induced degradation

As the efficiency of perovskite/Si tandem solar cells (PVSK/Si TSCs) surpasses the practical limit of single-junction cells, consideration of device stability is critical for real-world application. Demonstrated recently, potential-induced degradation (PID) and partial recovery can occur in PVSK/Si TSCs depending on the external potential, indicating that the hitherto underresearched PID issues must be addressed for successful commercialization.
