TECC-connect®
PV modules made from abundant materials
TECC-connect® is the first solar cell interconnection technology that completely eliminates the use of silver, lead, and bismuth.
Sustainable, RoHS compliant,
patented and scalable.
Ready for the PV future with
Tandem and backcontact cells.
Premiere: Intersolar 2025
Without silver
Without lead
Without bismuth
Ultra-Black Design
Silver
Silver is expensive, scarce, and environmentally problematic. The PV industry already consumes 14% of the world's annual demand – and the trend is rising.
Bismut
Bismuth is a byproduct of lead mining, banned in the automotive industry – and poses risks to the long-term stability of PV modules
Lead
Lead is toxic and prohibited under the RoHS directive – only solar modules are exempt. TECC-connect® eliminates this special rule.
