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. The workshop is organized within the FaiERA project (for details see below) and will take place at ISC Konstanz.

Eco-Solar press release: Even greener solar power on the way

Utilising solar cell materials that would otherwise end up on waste sites, is an important aim of the EU “EcoSolar” project, which is coordinated by SINTEF Research Scientist Martin Bellmann. Photo: SINTEF / Thor Nielsen

Europe wants to reduce its needs for raw materials and raise the level of recycling of resources in the solar power industry. If this project is successful, greenhouse gas emissions from solar panel manufacture will fall by 25 to 30 per cent.

“Our aim is that the solar cell industry should utilise materials that would otherwise end up on waste sites once solar cell panels are disposed of. We also want to make it possible to produce solar cell panels using less raw materials than we currently do.”

These are the words of SINTEF scientist Martin Bellmann, who coordinates the recently launched European Union project Eco-Solar. The project focuses on how the entire value chain in today’s solar power branch makes use of resources.
