Reducing the Cost of Thin Film Solar Module Production through Process Optimization
At the EU PVSEC DAS Environmental Expert GmbH will present its new technologies for waste gas abatement that will significantly reduce production costs in the solar industry.
Dresden/ Frankfurt am Main, September 24, 2012. DAS Environmental Expert GmbH, headquartered in Dresden, supports companies in the solar industry in significantly lowering their production costs. The environmental experts from Saxony will present one example of their systems at the world's largest trade fair for solar products: The 27th European Photovoltaic Energy Conference and Exhibition (EU PVSEC) in Frankfurt, Germany.
"The increasing price pressure within the solar industry poses a challenge to most of the sector's companies. We are continuously working on new solutions that will allow our clients to effectively lower their process cost", explains Dr. Andreas Frenzel, Director Research and Development at DAS Environmental Expert GmbH.
The Dresden environmental technology company together with Baoding Tianwei Solarfilms Co. Ltd. has optimized waste gas abatement processes during ongoing production operations. The Chinese company produces thin film solar modules on the basis of amorphous and microcrystalline silicon.
The manufacturing process employs large amounts of silane (SiH4), hydrogen (H2) and nitrogen trifluoride (NF3). To eliminate these toxic substances reliably from the waste gas stream, DAS Environmental Expert GmbH has combined two of their systems. The GIANT treats the waste gas by combining burn/wet technologies, the two processes of burning and scrubbing; the system was specifically developed for large waste gas flows. In a subsequent process the electrostatic dust collector (EDC) separates all remaining fine dust particles from the waste gas. The exhaust, after having undergone the abatement process, can be directly discharged to the atmosphere.
