WebThe Photovoltaic Industry. Arnulf Jäger-Waldau, in Solar Cells (Second Edition), 2013. 3.1.2 Fluidised Bed Process. A number of companies develop polysilicon production processes based on fluidised bed (FB) reactors. The motivation to use the FB approach is the potentially lower energy consumption and a continuous production, compared to the … WebThe fluidized bed process is used for coatings between 10-15 mils with the final thickness dependent upon part temperature and dip time in the powder. The film can be applied in thickness from 8-125 mils. This process requires pre-heat temperatures of at least 350°F and may require a post-heat or cure cycle.
These are the minimum elements to build a fluidized bed at lab scale, however industrial systems are of course more complex and can include the following : 1.
