Photon etc.. presents IMA™, a fast and all-in-one hyperspectral microscope suitable for analyzing solar cells and advanced materials in the visible (VIS), near-infrared (NIR), and short-wave infrared (SWIR) spectral ranges. Based on Photon etc.’s high performance tunable imaging filter, this imaging spectrometer delivers crisp images and exceptional data quality ideal for identifying defects and impurities in photovoltaic materials.
Notably, this hyperspectral imaging system features a patented absolute photometric calibration module that allows for the quantification of electrical properties, like the quasi-Fermi level splitting, solely through optical measurements. This eliminates the need for electrical connections or measurements while providing valuable insights into the materials' characteristics. Lastly, IMA’s global illumination is closer to sunlight illumination, providing information directly relevant to a device’s performance in the field.
Key Features
The main features of the IMA™ are:
- VIS, NIR and/or SWIR spectral ranges. One single instrument covering 400 nm - 1620 nm
- High spatial and spectral resolution
- 3D (spatial and spectral) mapping of photoluminescence (PL), electroluminescence (EL), absorbance, reflectance
- Quantitative PL and EL measurements
- MP s-CMOS camera / high-performance InGaAs camera
- Illumination module including up to 3 laser sources and halogen or Hg lamps.
- Scientific grade microscope
- Fast global hyperspectral imaging (no raster or line scan)
- PHySpec Software: acquisition and analysis – unlimited license included
- Customization available
Applications
The applications of the IMA™ are:
- Visualization of the chemical, structural and optoelectronic landscape in halide thin film photovoltaic devices.
- Mapping of inhomogeneities and defects by measuring the current transport efficiency to characterize their effect on electrical properties of cells (e.g. fill factor).
- Mapping of anomalous PL, the quasi-fermi level splitting (Δµ), series, and shunt Resistance (Rs, Rsh) to identify the ideal fabrication route that would minimize losses caused by laser patterning/ablation process.
