NAMEC Workshop: Nanotechnology & advanced materials for the Energy Union – Going circular

Advanced materials are key to tackle climate change, Energy Union and re-industrialization in Europe.
On the other hand, a large-scale transition towards circular economy is urgently needed in order to
avoid the depletion of raw material resources and reduce the impact of human activity on the
environment. This workshop aims at providing some insights from both industry stakeholders and
research organizations on how Europe is addressing the challenge of circular economy from the
perspective of clean energy materials.

Update reuse of silicon nitride crucible

Multicrystalline silicon is the dominant material used in photovoltaic technology for production of low-cost solar cells. Solar cells made of multicrystalline material make up a little over half of the worldwide solar cell market. The starting material is crystallised in fused silica melt containers and the obtained ingots are sliced into thin wafers to make solar cells.

Since silicon at high temperature reacts easily with almost everything, and due to purity and mechanical requirements, manufactures are restricted to very few crucibles materials. Therefore, fused silica and fused quartz glass remains the material of choice for crucible and mould applications because it is readily available in high purity form and little reactive to liquid silicon.

Update argon recycling

In the production of silicon ingots, argon is used as a purge gas to remove contaminants during ingot crystallisation. Gaseous impurities, if not removed, can react with the molten silicon leading to particle precipitation and contamination of the material. The argon purity, suggested for PV-manufactures, has to meet the Semi standard (PV6-1110), i.e. 99.999%. For a process cycle which last ~50 hours, typically 20-40 Nl/min argon gas is consumed and after passing through the furnace the argon is vented to the atmosphere. Read more…

FaiERA and ECOsolar combining efforts

Date and Venue: April 4th – April 6th 2016 at ISC-Konstanz, Germany

The Eco-Solar work package 3 technical meeting (M6) on solar cell processing, between ISC Konstanz, AIMEN and SoliTek is combined with a three days hands-on workshop on solar module fabrication and characterization related topics.
