2015-12-07 Ukraine: Continuous Technological Process of Solar Silicon Production by Plasma Pyrolysis


 

Continuous Technological Process of Solar Silicon Production by Plasma Pyrolysis


Description of the project offered: 
The existing problem. Among the materials for the production of solar cells leads the silica (about 90 %). It is expected that silicon will retain its dominance in photovoltaics in the coming decades.
The main obstacle to the development of solar energy will remain high, the cost of generating. The main causes of the high cost of solar panels - the price of silicon. Classic Siemens process "Chemical Vapor Deposition" (CVD), providing today the major part of solar silicon and used more than 50 years, brought to the theoretically achievable level, has exhausted its technological, technical and economic possibilities in large-scale production. Thus, for the further development of the solar energy the development of new technologies in large-scale production of cheap mono-crystalline silicon is extremely relevant. 
The proposed project will develop a new method that could reduce panel prices by about half. This method reduces energy costs for the production of solar cells through increased productivity, fewer production steps to ensure high quality of silicon.
This high-performance method of obtaining a cheap "solar" silicon based on plasma pyrolysis of precursor gas (monosilane, chlorosilane) with deposition of vapors of silicon in the liquid phase. In contrast to the Siemens process deposition of silicon from the products of pyrolysis of precursor gas is conducted in a liquid silicon layer that allows to increase the deposition rate by 10 times and more. 
Already done: Theoretical and laboratory studies indicate that any thermodynamic and kinetic restrictions and limitations of plasma pyrolysis of monosilane, chlorosilane at a temperature above the melting point of silicon by the vapor deposition of silicon in the liquid phase are absent. Minimum estimated power consumption for plasma-chemical silicon be 3 – 5 kW∙h/kg Si. The technology of plasma pyrolysis allows to organize a continuous process. When the net power of the plasma torch 100 kW can be obtained a capacity of about 25 kg/hour. 
The project will involve:
To produce plasma reactor on the performance in silicon of up to 100 kg/hour and provide the combination in one production line with the installation for growing the dislocation-free silicon monocrystals by the Czochralski method. To perform tests and prepare the technical documentation for the industrial line.
Expected result: Significantly to reduce the price of SoG-Si by reducing CAPEX and OPEX, to show scalability to large production volumes.
