Innovating Gigawatt-Scale PV Manufacturing in Europe

Cosimo Gerardi 3SUN Gigafactory
Catania, Italy

Scaling high-efficiency photovoltaic (PV) technologies to gigawatt-level production in Europe represents both a formidable technical challenge and a strategic imperative for energy sovereignty. 3SUN is leading this transformation, with a strong focus on the industrialization of silicon heterojunction (HJT) solar cells—renowned for their superior efficiency and long-term stability. To enable large-scale manufacturing, our research and development teams are advancing innovations in process control, next-generation equipment design, and sustainable material sourcing, systematically addressing the key bottlenecks that currently constrain throughput and yield.

In parallel, we are at the forefront of developing next-generation tandem solar architectures, specifically integrating HJT as the bottom cell with a perovskite top cell. Our research spans materials engineering, interface optimization, and rigorous reliability testing, all aimed at surpassing 30% power conversion efficiency and ensuring robust operational stability. We are also pioneering scalable deposition and encapsulation techniques to accelerate the industrial deployment of these tandem devices.

By integrating fundamental research with applied engineering, 3SUN is committed to accelerating the reshoring of Europe’s PV manufacturing industry. Our efforts are directed toward establishing a resilient, high-efficiency, and sustainable solar value chain, positioning Europe as a leader in advanced PV technology.

How and why prepare a project for the European Research Council – ERC?

Dr. Christine Courillon
«Synthetic Chemistry and Materials» Research Program Agent
ERC Executive Agency
Place Rogier, 16
B-1049 Brussels, Belgium 

The European Research Council (ERC) and its executive agency are recognized for funding cutting-edge research proposed by researchers from around the world working in all scientific fields.

Applicants, who may be of any nationality, commit to implementing their research project in Europe (in one of the EU Member States or one of the associated countries).

Within the framework of the "Horizon Europe" program, the entire process will be presented, including the new features of the 2026 calls and those planned for 2027: from application preparation to project implementation, including evaluation and contract signing.

Several stakeholders (principal investigators, evaluators) will be invited to share their "ERC" experience. 

Biography:

Christine Courillon followed PhD studies at CNRS and was a post-doctoral associate at the University of Austin, Texas, where she worked on the total synthesis of Ambruticine.
Christine returned to Paris at the University Pierre et Marie Curie where she defended an Habilitation to direct research in the field of stereoselective organic chemistry.
She then received a full professor position at the University Paris-Diderot where she developed radical heterocyclic chemistry.
In 2009, Christine left Paris for Brussels first as an innovation manager and then as the chair of the European project office at the Free University of Brussels. She joined ERCEA in 2015, as the "Physical & Analytical Chemistry" (PE4) panel coordinator and now coordinates the PE5 panel "Synthetic Chemistry and Material Sciences".
