Abstract
The chemical route for producing hyperpure silicon, referred to as polysilicon, is energy intensive. In this work two paths are analysed to reduce energy consumption during polysilicon deposition: reduce power loss and increase polysilicon productivity. The solutions proposed for reducing power loss are: enlarging the reactor capacities and increasing the wall reflectivity. The proposals for increasing the productivity are: working at the optimum deposition conditions, that maximises the polysilicon growth rate, and stopping the process at higher rod diameters. By doing so, the process uses the energy more efficiently.
