Development of novel process for producing high-purity silicon through designing solid/liquid interfacial reactions

Research Project Outline

Production of solar-grade silicon conventionally requires extremely high reaction temperature with long duration, which causes considerable drawbacks. In this research, we focused upon electrochemical approaches which take place at solid/liquid interfaces to directly reduce silica to silicon, and by detailed analysis and understanding from atomistic viewpoint, we optimize the reactions to develop comprehensive process for producing high-purity silicon material for solar cell applications. We also attempt to utilize diatomaceous earth as reliable source for producing high-purity silica for such an application.
