NEW TECHNOLOGY OF OBTAINING "SOLAR" SILICON WITH INCREASED ELECTROPHYSICAL PROPERTIES
Advantages over analogues:
The technology provides:
- Increase the lifetime of minority carriers (NCC) of the plates of "solar silicon in 1.5 - 2 times compared with single crystals by thermal treatment;
- Increasing the efficiency of "solar" panels by 21%.
The development stage readiness:
Ready for application
Description of the development: () developed
- Methods of physical and chemical modeling to select effective alloying elements for semiconductor silicon, which reflects the change in the interaction energy of the silicon atoms in the crystal lattice;
Vibora-temperature heating rate, cooling during manufacturing operations (diffusion impurity gettering annealing) in order to avoid phase transitions in the silicon defect structure formation and degradation properties elektrofizichnih;
-modes of heat treatment of single crystals and wafers of silicon doped into account the temperatures of phase transformations
