Monocrystal introduces new PERC aluminum paste specially designated for a dot laser pattern

Monocrystal, a leading global supplier of PV metallization pastes and synthetic sapphire, recently announced the launch of its new EFX-9X series aluminum metallization paste for Passivated Emitter Rear Contact (PERC) solar cells, specially designed for a dot laser pattern. New optimized paste content does not damage a passivation layer, and brings up to 17% higher local contact efficiency, compared to our previous EFX-series pastes. This results in overall cell efficiency gain up to 0.1%. Furthermore, the new product provides 30% lower consumption as compared to the market average, while maintaining high conductivity of an aluminum layer. EFX-9X series is an advanced solution for a dot laser pattern delivering our customers an excellent PERC solar cell performance. “In the light of current market trends and the growing demand for high-efficiency solar products we are striving to provide our customers with high-end solutions, such as a dot laser pattern for PERC solar cells. We are continuously upgrading our EFX-series metallization PERC-package in order to allow our customers maximize their product efficiency and production yields”, commented Vyacheslav Golovin, CTO of Monocrystal Pastes Division.
