Photoluminescence (PL) Imaging is a unique non-invasive inspection tool as it can be used in-line at many different steps of the cell manufacturing process. This facilitates the direct comparison of data obtained at one process step to data obtained at another. Additionally, PL imaging can be compared to electroluminescence (EL) imaging on finished cells using comparable equipment.
