On 31 January 2018 more than 80 people from 11 different countries attended the event Advancing PV: from passivation to contacts – A passivating contact workshop. The interesting presentations of the invited speakers together with the extensive discussion with the audience after each talk gave us a lot of food for thought, making this day a great success!
After the opening talk by Prof.dr. Wim Sinke (ECN / UvA) that put silicon PV technology development, including passivating contacts, in a new perspective, Dr. Lars Korte (HZB) gave a clear introduction on the physics and working principles of passivating contacts, e.g. by using the classical c-Si/a-Si:H heterojunction as a well-studied test case and metal-oxide based passivating contacts. The following speakers – Dr. Frank Feldmann (Fraunhofer ISE) and Dr. Mathieu Boccard (EPFL) – gave interesting, more in-depth talks on two very successful types of silicon-based passivating contact materials: polycrystalline silicon and thin film silicon.
After the lunch break that was combined with a lively poster session, Dr. Martin Bivour (Fraunhofer ISE) continued the program with his talk on passivating contacts based on metal oxides. Finally, Dr. Thomas Allen (KAUST) gave an in-depth presentation that covered electron-selective passivating contacts involving relatively new materials, such as Ca, metal fluorides and many others.

I’m Dr. Eun-Chel Cho working at SunKyunKwan University in Korea. My group led by Prof. Jun Shin Lee is studying on silicon heterojunction. Recently we are working on carrier selective contact , supported by Korean government. I would like to the slides of the presentations, if possible. Also please let me know when the next workshop start.
Dear Dr. Eun-Chel Cho, thanks for your interest in our workshop and it is good to know that your group is also actively working on passivating contacts now! For some contributions we obtained permission to share the material only with the attendees of the workshop, so unfortunately I cannot provide you with the slides of the presentations. Since we received very positive feedback from the participants regarding a possible follow-up of this workshop, we are thinking about a possible next edition of the workshop, but no final decisions have been made yet. In the meantime you are welcome to join our new LinkedIn group “Advancing PV: from passivation to contacts” where all members are free to post interesting updates on passivating contacts and where we will also post messages regarding new initiatives.
