Degradation detection as a result of ageing organic solar cells by thermography

In this work, two types organic solar cell (OSC) modules (with diferent organic semiconductor layer - zinc phtalocyanine (ZnPc) and DPP(TBFu)2-C60) are studied for determination of the effects of degradation in different zones of the OSC. Therefore is used thermographic approach for the monitoring and characterization of this effects. The dynamic infrared thermography is imposed as effective approach for diagnosis of solar cells and for detect invisible sub-surfaced defects. A method for digital processing with LoG filter is presented.
