AIKO Receives First TÜV SÜD Certification for a BC Module in Explosion-Hazard Environments

AIKO has reached a significant milestone – its ABC Stellar 66-cell dual-glass module featuring back-contact technology has become the world’s first BC photovoltaic module to receive explosion protection certification from TÜV SÜD.

What the Certification Means for Industry

The certification confirms that the module does not act as an ignition source in environments with flammable gases or explosive atmospheres. This opens the door for installations in demanding industrial environments such as:

  • Oil & gas facilities

  • Chemical plants

  • Fuel stations

  • Storage terminals

In the European context, this represents a major step forward. Strict safety regulations often limit PV installations in classified explosion-hazard zones. Verification by an internationally recognized authority helps align safety compliance with the growing pressure to decarbonize industrial operations.

Technical Basis of the Safety Concept

The module combines increased safety principles (Ex e) with an innovative back-contact cell design. It incorporates reinforced insulation, optimized creepage and clearance distances, and advanced temperature control to minimize the risk of sparking and hotspot formation.

The advanced copper interconnection technology further reduces the risk of microcracks, enhancing long-term reliability.

Implications for the Development of Photovoltaics

This certification marks an important step toward broader deployment of PV systems in industrial sectors with high safety requirements. The combination of high efficiency and verified safety expands installation possibilities in locations that were previously restricted by regulatory constraints.

For energy-intensive industries, it provides a viable pathway to decarbonization without compromising operational safety.
