Carbon and ISC confirm cooperation for gigawatt production with TopCon and IBC technology

The French company Carbon has confirmed its cooperation with the Konstanz, Germany-based International Solar Energy Research Center (ISC Konstanz). This had already become known in early March when Carbon published its plans to build a solar factory with initially five gigawatts (by 2025) and later (by 2030) 15 gigawatts annual capacity for ingots, wafers, cells and modules. In the meantime, 20 gigawatts have been named as the target. In mid-April, Carbon had announced a cooperation with French industrial equipment specialist ACI Groupe for this purpose (our news of April 21).
According to Carbon, the partnership with ISC is aimed in particular at TOPCon solar cells (Tunnel Oxide Passivated Contacts), which are seen as a potentially dominant technology in the near future. ISC’s expertise in IBC (Interdigitated Back Contact) solar cells is also highlighted in the announcement, as is the institute’s research into advanced, cost-effective production processes for solar modules.
