Description
The lock-in thermography tool is used mainly to identify shunts in solar cells. This system is equipped with an infrared camera that has a spectral range from 1.1 μm to 5.3 μm and a frame rate of 100hz, an LED array that works at 850 μm, a power supply, and a computer. Dark Lock-In Thermography (DLIT) and Illuminated Lock-In Thermography (ILIT) produce images that can detect shunts and high recombination areas. When combined with image processing software like “Local-IV” and “RESI” a precise quantitative map of sheet resistance for a complete solar cell can be produced.
