Identify spatial inhomogeneities in solar cells with confidence

PL, EL, lock-in thermography and electrical characterisation in one compact platform.


Vitios combines photoluminescence (PL), electroluminescence (EL), infrared imaging and electrical characterisation (JV, impedance) with software for seamless measurement customisation and embedded post-processing. It enables spatially resolved analysis of solar cells beyond standard electrical measurements.

  • Spatially resolve inhomogeneities not visible in JV measurements

  • Combine PL, EL, DLIT, ILIT and SS-DLIT with electrical characterisation

  • Perform 4-wire JV and impedance spectroscopy measurements

  • Analyse recombination, charge extraction and dissipative losses

  • Apply transient and steady-state imaging for perovskite devices


Beyond JV measurements

Solar cell scale-up, stressing experiments and new deposition methods directly impact device performance as estimated by JV measurements. However, electrical measurements do not provide spatially resolved information.

Vitios enables imaging-based analysis to locate and identify spatial inhomogeneities in films and full devices.

Vitios is ideal if you:

  • Publish or plan to publish solar cell imaging or characterisation data

  • Work on perovskite, thin-film, or tandem solar cells

  • Need to identify spatial inhomogeneities, defects, or recombination hotspots

  • Want to correlate imaging results with JV and impedance measurements

  • Study ion-driven transients, degradation, or scale-up challenges
