Alternatively, the high sensitivity provided by EMCCD sensors in the near-infrared (NIR) spectral range is also capable of detecting the electroluminescence signal. Setting a short exposure time allows for the generation of more than 10 fps (depending on the polarization current).
The images below compare CIGS (Copper Indium Gallium Selenium) solar cells measured with EMCCD and SWIR sensors (excited with the same bias current). The results have been used to characterize the solar panels during their manufacturing process.
Preventive maintenance of a photovoltaic plant requires the ability to quickly identify solar panels with defective cells that are reducing the plant's overall efficiency. Raptor Photonics scientific cameras are ideal for this type of application.
By injecting a reverse bias current into the system and rapidly scanning in video mode (using either an InGaAs or EMCCD sensor), a large number of solar panels can be inspected quickly and reliably. Damaged or less efficient cells will appear immediately, allowing for the identification of panels that need to be replaced to restore overall efficiency.
