Abstract; Grain boundary (GB) recombination is a controlling factor in the electronic properties of polycrystalline silicon. We would like to report computer modeling of the variation of electron transport parameters with depth, under illumination. The GB barrier height (Vg) versus photogeneration rate G and depth are presented, along with the resulting electron lifetime (π), mobility (µ) and diffusion length (L). Under AM1 illumination, Vg increases whereas -π, µ and L all decrease drastically with increasing depth. The GB trap density is used as a parameter, and strongly influences transport parameters in both dark and light cases.
