Electro-optical Characterization Laboratory

The laboratory is dedicated to the characterization of optical and photovoltaic materials and devices for high-efficiency photovoltaic systems. The main types of measurements include:

 

  • Photoluminescence measurement at room temperature to evaluate material quality, doping levels, and optical couplings between sub-cells of multi-junction photovoltaic devices.
  • Measurement of spectral response and quantum efficiency of single- and multi-junction photovoltaic devices to evaluate the current produced as a function of incident wavelength, including under light concentration conditions.
  • Current-voltage (indoor) characterization of single- and multi-junction photovoltaic devices using solar simulator to evaluate photovoltaic performance based on incident radiation.
  • Light reflectance and transmittance measurement to analyze the optical characteristics of substrates, photovoltaic cells and optical components used in solar concentration, considering wavelength and angle of incidence
