Noise and optical activities of local defects in solar cells pn junctions

This paper deals with the study of monocrystalline silicon solar cells noise and optical characteristics and correlation between them with respect to solar cells diagnostic purposes. The study was focused on finding of local defects in reverse-biased solar cells pn junctions and making their characterization. The next goal was to attribute the individual founded defects behaviour to the physical mechanisms occurring in the reverse-biased pn junction.
