Technical approach

As reported
ABC technology

All back contact, high efficiency

Metal contacts on the back surface only. Front clear of shading metal. More light reaches cells, boosting efficiency to 25%.

Low-silver metallization

Cheaper contacts without sacrificing conductivity

Silver-free and low-silver metallization cuts material costs and environmental impact while maintaining current carrying capacity.

Vertical integration

Control from ingot to customer

AIKO manages own supply chain for cells and modules, allowing rapid technology rollout and consistent quality.
