Abstract: Electroluminescence (EL) is a laboratory technique able to provide detailed information on defects in solar cells, while infrared imaging (IR) is much easier to be applied in the field. A statistical analysis of IR and EL images for different types of damaged solar cells, is herein proposed in order to understand if EL and IR data can be correlated to each other. Results show that dark IR images, characterized by a slight variation in temperature, provide few local information, while illuminated IR images are promising to distinguish between classes of damage in line with EL data.
