PV solar cell manufacturers constantly need to reduce processing cost, which are dominated by material consumption such as metallization pastes, notably with PERC solar cells. However, high adhesion for tabbing applications is required for greatest long-term reliability.

Solution

MY-555 was specially developed to be a low-cost alternative metallization paste for PERC solar cells with an efficient balance of silver content and paste consumption. MY-555 has 55% silver content along with 6% lower consumption per wafer to allow for a 10-15% cost of ownership reduction. MY-555 is claimed to provide up to 50% higher adhesion resulting in enhanced production yields which also contributes to cell and module reliability.

Applications

Back-side silver metallization paste for PERC solar cells.

Platform

MY-555 PERC silver metallization paste is formulated to be compatible with Monocrystal’s EFX-series back-side aluminum PERC pastes. Monocrystal’s PERC package allows customers to boost efficiency gain up to 0.18%. MY-555 does not penetrate the passivation layer and better protects the emitter during the metallization process. Monocrystal PV has the latest edition of ISO 9001 certificate by TÜV SÜD Shanghai.
