Internal gettering of iron, by a low temperature annealing process, has been shown to be effective in reducing the interstitial iron concentrations and thus improve the minority carrier lifetimes in both mono- and multi- crystalline silicon materials [1-4].
In multicrystalline silicon (mc-Si), the precipitation sites are mainly the structural defects within the material.
In our future work, the Fe precipitation mechanism will be examined for different types of structural defects in mc-Si materials.

To determine if the obtained material was stable or not, the disk was further annealed up to 1200°C.
The materials exhibited reasonable hardness, which was sufficient for a wide range of applications.
