We have developed in-house semiconductor solvers to simulated solar cells under Matlab environment.

Figure 1. summarizes the abilities of these solvers (single junction, multi-junction, 1D, pseudo-3D, custom material library...)

More information is given in [1-4]. Read more about the 1D solver, click here.

1. Solar cells measurements

  • I-V measurements under dark, 1-sun (AM1.5G) and low concentrations (> 50 suns),
  • Spectral response measurements (external quantum efficiency) for single and multi-junction solar cells,
  • Electrical measurements (TLM, C-V measurements),
  • Reflectance measurements by UV-Vis-NIR spectrophotometry (for the evaluation of antireflection coatings e.g.).


2. Transistors measurements

under construction

Several modeling tools have been developed in our team under Matlab environment. The aims was to understand the PECVD growth of materials, to understand the electrical transport in nanocrystalline materials and to understand and predict the behavior of solar cells.

  • Modeling of solar cells:

1D and pseudo-3D modeling tools have been developed to characterize single and multi-junction solar cells under low and high concentration rates. read more...


  • Modeling of material growth:

Modeling of the PECVD growth of nanocrystalline silicon has been developed and allows to reproduce the conic shape of the Si nanocrystals as well as the top morphology [1]:



  • Modeling of electrical transport in amorphous semiconductors [1]:
