Silicon Materials Workshop
4th Silicon Materials Workshop and
11th International Workshop on Crystalline Silicon for Solar Cells
New date: April 20th – 22nd 2022 In Lisbon, Portugal
Physical event of the CSSC and SiMat workshop
It is with great pleasure that we announce the new date for the physical event of the joined SiMat and CSSC workshop.
A remarkable feature of the CSSC and SiMat workshop are the direct interaction and discussion among the participants.
COVID-19 has dramatically affected our life.
We are sorry for the inconvenience the changes have caused and we are looking forward to see you in person in Lisbon next year.
Joao Serra and Gianluca Coletti.
Call for Abstracts: September 2021
Conference date: April 20-22, 2022
This year and for the second time, we offer the participants of the SiMat and CSSC workshops a joint and unique virtual event hosted by the University of Lisbon in Portugal, (April 20-22, 2022). The CSSC workshop focuses on the silicon material and the substrate with strong attention on crystallization. The SiMat workshop focuses on the connection between silicon materials and cell and module technologies. Combining the two workshops will create a fantastic opportunity to exchange knowledge and insights between industrial and scientific participants from the two communities. The program will include invited and contributed oral and poster presentations in addition to open forum discussions on selected topics.
Welcome to a unique silicon for photovoltaics online event.
Topics to be covered at the workshop are:
• Fundamental materials science related to crystalline silicon solar cells
• Silicon feedstock technologies
• Crystallization of multicrystalline, quasi-mono, monocrystalline silicon
• Advanced wire sawing and emerging kerfless technologies
• Novel materials and processing for advanced cell architecture
• Impact of silicon material to performance of cell, module and PV system
• Degradation phenomena related to silicon materials on cell and module performance (e.g. LID, LeTID, PID, hotspot, etc.)
In the past, CSSC was held in Sendai, Japan (2006), Xiamen, China (2007), Trondheim, Norway (2009), Taipei, Taiwan (2010), Boston, USA (2011), Aix-les-Bains, France (2012), Fukuoka, Japan (2013), Bamberg, Germany (2015), Tempe, USA (2016) and Sendai (2018).
The SiMat was held in Amsterdam, the Netherlands (2008), Rome, Italy (2013), Tempe, USA (2016).

Reasons for the Si-Materials workshop
The Si-Materials workshop series target specific issues in the field of crystalline silicon materials for photovoltaic applications. The workshop presentations and discussion sessions rotate around this topic.
The workshop’s main character is to be at the interface between silicon material technologies and cell- and module technologies.
The first workshop was organized in Amsterdam, the Netherlands, in 2008. The focus was on solar-grade feedstock specifications. At that time the poly-silicon shortage necessitated the redefinition of solar grade silicon and its specifications. The workshop resulted in a tentative and approximate standard set of specifications for solar grade silicon suitable for the fabrication of solar cells which were taken as basis for the discussion and the formulation of the SEMI standard on polysilicon issued in 2009.
The second workshop was organized in Rome, Italy in 2013 and focused on the challenges for Si materials. The main debates were around mono- and multi-crystalline silicon from the different perspective of wafer, cell and module producers and customers in a market dominated by oversupply of PV modules. The outcome was reported in the editorial of a special edition of Solar Energy Materials and Solar Cells, Volume 130, November 2014, from page 629.
The third workshop was organised in Tempe, Arizona, USA. in 2016. The market situation has changed again. The PV industry was coming out from dark economical and financial situations. It was the time where new technologies were to be implemented to keep and further increase this positive trend. The focus was to discussion and debate over new technologies available and in R&D phase for the PV industry. In this market situation, an often mentioned topic was and still is the ongoing debate between p- and n-type silicon together with silicon defect mitigation processes. These topics was the core of the Si-Materials workshop 3rd edition.
