Aluminum pastes for PERC cell design

Monocrystal aluminum pastes for PERC

Monocrystal aluminum pastes for PERC cell design provide efficiency gain of up to 0.15% and excellent adhesion, while having lower laydown rate.

Cell efficiency is the main priority for solar cell manufacturers. The switch to PERC cell design is one of the most attractive ways to deliver higher solar cell efficiency. Monocrystal was one of the first to introduce aluminum paste for PERC cells in order to meet growing market demand. We have been supplying pastes for PERC technology for more than 7 years.

Monocrystal supports collaborative R&D projects, customizing pastes for specific customer needs. Latest advanced paste solutions allow both PERC cell efficiency gain of up to 0.15% and lower paste laydown rate.

EFX-Series aluminum pastes for PERC are applicable for combined firing with other metallization components, and have good compatibility with other Monocrystal products.
