Optoelectronic Modelling (IMAGE)
Caption
- Combined experimental characterization and physics-based modelling of the certified 24.6% perovskite/CIGS tandem reveal CdS/CIGS interfacial recombination and perovskite bulk defects induced by surface roughness.
- Stepwise optimization integrating calibrated simulations with a data-driven Shockley–Queisser analysis demonstrates an efficiency potential exceeding 35% through targeted defect passivation and optical refinements.
- Controlled bandgap tuning further enhances both the achievable efficiency and annual energy yield, provided the material quality is preserved across the full device stack.
