After PEPPERONI’s successful contribution to three international conferences in September, the events scheduled for October are shifting the focus towards hands-on activities with active participation and technical demonstrations. Starting with PEPPERONI’s 6th General Assembly, which will bring together 14 project partners, two workshops will follow at the end of the month: the 13th Metallization & Interconnection Workshop and the 2nd edition of the Spatial Atomic Layer Deposition Day.
6th General Assembly
From 7-8 October 2025, PEPPERONI partners will gather at the Eindhoven University of Technology (TU/e) in the Netherlands to discuss the project status and hold poster sessions on perovskite materials, cell-level, module-level and pilot line developments. Technological parts will be complemented with insights from indoor and outdoor testing, as well as from life cycle assessment. The event, including a lab tour, is hosted by the Plasma & Materials Processing group of the Physics Department at TU/e, renowned in the field of atomic-scale processing with a particular emphasis on atomic layer deposition (ALD) and spatial ALD.
13th Metallization & Interconnection (MIW) Workshop
From 20-21 October 2025, the annual and well-established MIW workshop will take place in Berlin-Adlershof, Germany. This year’s edition includes a special industry session related to the PEPPERONI project that focuses on the metallization and interconnection of silicon-perovskite tandem solar cells. The shared session is co-organised with PEPPERONI partners from Helmholtz-Zentrum Berlin (HZB) and project coordinator Bernd Stannowski, featuring HZB’s recent results with a presentation by Freya Leyland on “Investigating barrier properties of TCOs against metallization and interconnection materials for thermal stability of perovskite-based solar cells”.
Another highlight of this year’s workshop includes the lab tours at the end of the day on Tuesday, 21 October 2025, which will allow participants to see the equipment used for the development and fabrication of silicon-perovskite solar cells, as well as actual indoor and outdoor solar cells testing setups. The infrastructure includes a new light soaking ring, climate chambers, UV testing and a photoluminescence imaging tool for perovskite and tandem cells.

2nd Edition of the Spatial ALD Day
On Tuesday, 28 October 2025, TU/e will host the next Spatial ALD Day, which will bring the research community together once again for a day of insightful discussions, deep technical dives and networking. This free event is co-organised with the EU PEPPERONI consortium and the Open Technology Programme (OTP) project on spatial ALD from the Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO). TU/e will also highlight its work within the PEPPERONI project that involves the development of temporal and spatial ALD processes for large-scale, cost-effective manufacturing of perovskite/silicon tandem solar cells and modules. The day will start with a tutorial session on (spatial) ALD, followed by scientific highlight talks. After lunch, there will be contributions by many spatial ALD companies in the fields of precursors, PV, batteries, catalysis, membranes, and optics and photonics. The day will be concluded with a lab tour at the TU/e premises and a networking dinner.
