Photovoltaic devices

Research activities:

  • 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.

  • Characterization of solar cells with different structures and layer composition, both polymeric and dye-sensitized solar cells; External and Internal Quantum efficiency measurements; Advanced characterization techniques such as: electroluminescence; thermal characterization; Impendance Spectroscopy (IS); Deep level transient spectroscopy (DLTS); Open Circuit Voltage Decay (OCVD); applied bias voltage decay (ABVD).
  • Impendance model of organic/hybrid solar cells. 1D/2D simulations.
  • Reliabilty study of polymeric and dye-sensitized solar cells by means of electrical, thermal, illumination and UV exposure stresses.
