Solar-Check

MoviTHERM Solar-Check is a turnkey infrared non-destructive testing (irNDT) system developed for solar cell inspection that includes an infrared camera, excitation source, and image processing software. The built-in lock-in thermography (LiT) measurement technique responds to thermal responses from the solar cell at the exact excitation frequency, thereby dramatically improving the overall sensitivity of the system to micro-Kelvin levels. Additionally, the LiT technique is not susceptible to the adverse effects of reflections or thermal diffusion significantly enhancing the appearance of defects. Solar-Check can be used for all common IR solar cell testing methods including crack detection, shunt detection, emission analysis, and carrier density measurements.

Solar-Check Functionality

Solar-Check works by means of Lock-in Thermography (LiT) which consists of applying a periodic pulsed electrical signal to the test device and monitoring the resultant temperature variation with a synchronized thermal camera. A computer captures multiple IR images and applies a processing algorithm to produce a surface map identifying localized hotspots. LiT produces images with greater resolution and temperature distribution over passive IR thermography.
