TECC-connect®
PV modules made from abundant materials
Sustainable, RoHS compliant,
patented and scalable.
Ready for the PV future with
Tandem and backcontact cells.
Premiere: Intersolar 2025
TECC-connect® is the first solar cell interconnection technology that completely eliminates the use of silver, lead, and bismuth.
PV modules
from abundant materials
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.
