Abstract. This work shows that the introduction of nickel atoms in the process of growing silicon crystals enables to obtain a material with stable electrophysical parameters during thermal annealing in the wide temperature range 450…1050 °С and duration (t = 0.5...25 hours). This is the most cost-effective way to create material for semiconductor devices and solar cells with stable parameters.

Keywords:silicon, thermal donor, nickel, doping, thermal stability.
