摘要

The aim of this work is to develop a reliable and precise non-destructive characterisation method for devices testing using infrared thermography. Our method is aplied to submicronic junction solar cell characterisation. Two types of measurements are tested and compared: a static method and a pulse method. Both give similar results but obviously the pulse method is faster. In order to determine the temperature of the different parts of the structure with accuracy, emissivity and transmission measurements have been performed. An example of the characterisation is presented showing the precision of the method.
