Current obstacles

Cost competition from other 25% makersLONGi and others achieve 25%. AIKO must stay ahead on metallization cost to maintain margin.
Supply chain for silver-free contactsScaling non-silver metallization requires suppliers and process control; flaws risk performance.

Physics limits

Silicon cell efficiency ceilingCrystalline silicon cells have ~29% theoretical maximum. ABC approaches this but cannot exceed physics.
Metallization parasitic resistanceThin metal lines carrying current have electrical resistance, causing losses. Thicker lines reduce losses but cost more.

How it works

3 parts

Back contact design

Move metallic contacts to the rear

Metal fingers on the front shade cells. ABC moves all contacts to the back, leaving front clear. More sunlight boosts voltage and current.

Silver-free metallization

Use cheaper conductive materials

Instead of silver paste, AIKO uses silver-free or low-silver metallization. Lower cost per watt, keeps electrical performance high.

Mass production scaling

High-volume manufacturing

AIKO has scaled ABC to hundreds of GW per year, proving design is cost-competitive at scale.
