study effect of temperature on distribution of H atoms in hydrogenated silicon substrate

What is it about?

Many theoretical studies have been performed to characterize hydrogenated silicon . However there is no theoretical study of the hydrogenation process reported. The study we present here is aimed to explore how hydrogen atoms absorbed by silicon substrate during hydrogenation and how hydrogen atoms are distributed in silicon after hydrogenation process finish. We also want to study how temperature effects on the process in a-Si and c-Si.

Why is it important?

Crystalline silicon and amorphous silicon are main materials of solar cell. Under prolonged exposure to light, silicon will degrade in quality. Hydrogenation is believed can minimize this degradation by reduce the number of dangling bond. These Molecular dynamics simulations are aimed to elaborate the hydrogenation process of crystalline silicon and amorphous silicon and to elucidate effect of temperature on distribution of hydrogen atoms
