Back-Contact’s Move to the Front

View Webinar Video

Back-contact technologies – metal wrap through (MWT) and interdigitated back contact (IBC) modules – promise high energy yields per square meter and are already making a significant impact in markets for residential rooftop and small commercial PV. In this pv magazine Webinar, we partner with leading materials company DSM for a closer look at how these technologies differ from conventional module designs, and the technology roadmap that could lead to bigger market impacts over the coming years.


Back-contact’s move to the front

At the sharp end of cell and module efficiency, a number of different technologies promise the highest energy output over the smallest area. And not least among these are the back-contact technologies, metal wrap through and interdigitated back contact.

For the rooftop segment in particular, where these technologies offer the added benefit of more aesthetically pleasing designs compared to standard modules, MWT and IBC have already begun to gain market share.

In this pv magazine webinar, we will take a closer look at back-contact technologies and their position in the market for high-end modules. On the technology side, the program will explain the inner workings of back contact modules and how these differ from conventional PV products. We’ll hear from Hugo Schoot, Director Strategic Partnerships at DSM Advanced Solar, about the market development of high-efficiency modules, the commercial benefits of back contact modules, and the essential contribution that DSM’s conductive backsheet makes toward achieving these.

Next, we will bring in even more commercial experience with a presentation from Paolo Maccario, President and CEO of Silfab Solar. Silfab produces metal wrap through modules incorporating DSM’S conductive backsheet at its manufacturing base in the U.S. Both its conventional and back-contact modules have achieved ‘Top Performer’ status in PV Evolution Labs’ module scorecard. Maccario will share some insights from Silfab’s two years of experience running large-scale back contact production, as well as details of the technology’s future roadmap. He will also present a use case comparing the performance of MWT-modules with standard modules.

And we will also hear from Radovan Kopecek, CTO and co-founder of solar research institute ISC Konstanz. Kopecek and his team developed the ‘ZEBRA’ IBC cell concept, and he will share some of its advantages with the webinar audience, as well as plans for the next generation of ZEBRA, which is set to drive back contact technology’s production costs even lower, making it competitive in even more markets.
