Electroluminescence Camera Systems


Electroluminescence camera systems are available for imaging cracked cells and other defects in still images or video. Solutions are available for the lab from small R&D cells to full modules, and travels systems are available for outdoor testing.  Systems come with a modified DSLR camera, filters, lens, tripod or stand, laptop or tablet computer,  power supply, MC4 cables to place between power supply and solar panel, and instructions for use and image enhancement.  



UV Fluorescence Systems


UVF is a fast method to detect cell cracks in aged modules.  We offer a low-cost handheld flashlight kit for detection by eye, and a high-throughput camera flash based system with throughputs up to 1000 modules/hour.





Photoluminescence Wafer and Cell Tester

Safe red LED lightsource and high resolution PL camera within a lightproof enclosure to obtain contactless images of wafers and cells.  Can be configured to look at a single cell within a module.










The LoadSpot performs static and cyclic (dynamic) load tests for standard IEC certification testing.  The bending tests are performed by applying vacuum or air-pressure to the rear side of the module, thus leaving the front side open for EL and IV testing.  For standard panels, applying a light vacuum to the rear side allows for a quick crack-opening test to predict future degradation were the closed cracks to become fully open in the field.

Fast measurement of contact resistivity for solar cell grid structures.  More accurate and lower variability than using manual probing.  Also measures line resistivity.


More info





Nondestructive contact resistance measurements. 

Measure resistance between metallization and the silicon wafer
Hide test patterns within busbars (no cosmetic or efficiency effects)
Automatic alignment of probehead to test patterns
Standalone or in-line applications
Test every cell on a production line (<3 sec takt time)
Adaptable to in-line or rotary table automation
