Longi Backs Carbon’s Shift to GW-Scale Solar Production in France

France-based startup Carbon has announced a significant revision to its plans for establishing a gigawatt-scale solar module factory.

Initially, Carbon intended to develop its solar modules using an independent n-type tunnel oxide passivated contact (TOPCon) technology.

However, the company is now pivoting towards a strategic partnership with Chinese solar manufacturer Longi, a global leader in photovoltaic technology.

This collaboration involves adopting back-contact (BC) solar technology, which is known for its efficiency and reliability in module performance.

The shift reflects Carbon’s ambition to scale production rapidly and leverage Longi’s established manufacturing expertise and supply chain capabilities.

By integrating BC technology, Carbon aims to enhance the energy conversion efficiency of its solar modules, making them more competitive in the growing renewable energy market.

The partnership also aligns with France’s broader goals of expanding domestic solar manufacturing capacity to support the country’s renewable energy targets.

Longi’s support is expected to accelerate Carbon’s factory development timeline and improve the quality and output of solar modules produced.

This move underscores the increasing importance of international collaboration in advancing solar technology and scaling clean energy infrastructure.

As the solar industry continues to evolve, Carbon’s revised roadmap highlights the dynamic nature of technology adoption and the strategic decisions startups face to remain competitive.

The collaboration could also serve as a model for other European solar manufacturers seeking to combine local production with global technological leadership.
