Characterisation of Photovoltaic Cells and Materials

Analysis, characterization and diagnosis of photovoltaic devices of any technology (from crystalline silicon wafer, a-Si, CIS, CdTe, III-V, OPV …) and different materials.

 Electrical, optical and structural materials assesment

• Sheet resistance, thickness maps (up to 15cm x 15cm). Perfilometry, mechanical properties
• Spectral ellipsometry, reflectance and transmittance (spectrally resolved).
• Sinton, DLTS, PCD, LBIC.
• SEM-EDX, AF

Photovoltaic cells diagnosis and characterization

• I-V curve and power determination (as of IEC-60904).
• Spectral response.
• Lock-in thermography.
• Electroluminiscenc
