Year-long test identifies degradation mechanisms in perovskite tandem solar cells

Researchers from TNO and Fraunhofer ISE ran a 1-year outdoor test of perovskite/perovskite/silicon triple-junction solar cells and found a clear efficiency decline from 17–18% to 13–14% driven by multi-stage degradation.
