Abstract
Very little literature is today available describing defects and failure mechanisms in a photodiode. The study of defects is
very important, as they can significantly reduce the performances of the photodiode. The reason for the lack of data in this
field is the fact that the defects, that increase the dark current and reduce the photogenerated current, are not understood
well enough to enable the development of a general model. In this paper we performed an analysis of the defects and
failure mechanisms in the photodiode, pointing out their characteristics and their influence on the parameters of the
photodiode (photogenerated current, dark current).
