Silicon Materials Workshop
4th Silicon Materials Workshop and
11th International Workshop on Crystalline Silicon for Solar Cells
Unfortunately, due to the international situation regarding the spread of the COVID-19, the safety and health of the participants let alone the travel uncertainties, the International Advisory Committee of both the CSSC and SiMat workshops decided to cancel the 2020 edition of the combined workshop.
Later this year the new date for next edition of the combined workshop will be announced.
We are looking forward to meet you in person and welcome you in Lisbon in 2021.
Joao Serra and Gianluca Coletti
The contributors of the current program are encouraged to submit their work to a journal of choice and to submit an update of their contribution to the next workshop edition.
Authors whose contributions were selected for submission to the special issue of SOLMAT have the option to submit right away their work to SOLMAT or wait for the special issue linked to the next workshop edition.

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.
