• Investigation of advanced solar cells based on silicon: PERT, PERC, MWT, bifacial solar cells; optimization of the layout, antireflection coating, IQE, EQE, reflectivity, CV characterization.
• Solar cells on III-IV, CdTe, InGaN: material and device characterization based on C-V, DLTS, photocurrent spectroscopy, light/dark I-V, electroluminescence measurements.
• Reliability of solar cells, definition of models for the dergadation processes, analysis of specific mechanism including: potential induced degradation, degradation under reverse/forward bias, impact of moisture/temperature.
