A model of the decay kinetics of photoconductivity in amorphous hydrog
enated silicon, in which recombination of excess carriers is assumed t
o occur via tunnelling, is proposed. It is shown that study of the dec
ay shape after flash illumination can be a very effective way to detec
t structural inhomogeneities in amorphous or disordered semiconductors
