The slow grind of FBR polysilicon

FBR Poly: Fluidized bed reactor (FBR) technology has been hailed as a means to produce polysilicon for solar at lower costs and with a small fraction of the electricity used by the dominant Siemens process. However, long delays at two new projects and technical challenges are slowing the progress of this promising technology. Will FBR eventually deliver?

The International Technology Roadmap for Photovoltaics (ITRPV) by SEMI is one of the core technical resources for the solar PV industry. Published annually, the document includes research from a range of manufacturers and covers expected developments in technology from polysilicon to modules. The 2013 ITRPV predicted that the market share of FBR polysilicon would rise …
