In this paper we discuss and model the effects of the density of defects in hydrogenated amorphous silicon from an electronics point of view. To this end, we have created a SPICE model that accounts for the two main field effects, Poole-Frenkel and tunnel, responsible for the leakage current. The comparison between our model and the experimental data shows that our approach allows a quick evaluation of the quality of the device with no need to run a complete steady state measurement. Also, we have validated our SPICE photodiode model by implementing it into a three CMOS simple pixel structure.
