Silicon for solar cells – scale-up and material recycling
The purpose of this project is to validate the technical and commercial potential in a new method to manufacture feedstock for silicon solar cells. The method is expected to generate the same product purity as traditional purification methods but at much lower costs and with a much lower consumption of energy.
The overall purpose of the project is to investigate and exploit the technical and commercial potential of a new method to purify Metallurgical Grade Silicon.
In the previous phases of this project a small R&D processing line was designed, build and operated with the purpose to study and improve the purification efficiency of the process.
In addition it’s being investigated, if the process can be used to obtain Solar-Grade purity silicon feedstock and a validation hereof is planned through chemical analysis and by external manufacturing of crystalline silicon solar cells.
At the same time a business plan is being developed that describes the commercial potential of the technology as well as a roadmap towards commercialisation.
The objective of the current project phase is to demonstrate, that manufacturing methods suited for low cost massproduction of solar-grade silicon has been identified and that processes for cost efficient recycling of side-streams can be implemented.
Two previous phases of the project was designed, built and operated a small R & D process line with the objective to investigate and improve the chemical cleaning efficiency of the new technology. It was also studied whether the process can deliver solar-grade purity silicon and a validation will be carried out by chemical analysis of purity and through external production of crystalline silicon solar cells.
Simultaneously, a business plan, which describes the commercial potential of the technology and a roadmap toward commercialization, was prepared.
The objective of the current phase of the project was to demonstrate that cost-effective manufacturing methods suitable for mass production of solar-grade silicon have been identified and that the processes for cost-effective management of the various side streams can be implemented.
