    Merck’s isishape pastes ensure homogeneous and well controllable etching, leading to an efficiency gain of 0.5%.

    RENA’s cleaning technology InClean is specially designed for Merck’s isishape and ensures a perfect match between consumable, process and equipment platform. RENA’s InClean is available as an upgrade for existing lines or can be integrated into a RENA InOxSide tool for junction isolation and PSG removal (PSG: Phosphor Glass).

    CSI has adopted the new advanced solution for its high-efficiency p-type cell technology. The company successfully integrated the new concept into its mass production. Top solar cell efficiency of 21.1% was achieved on Cz (monocrystalline) solar cells by implementing the technology in the ELPS high-efficiency cell structure (ELPS: Efficient, Long-term Photovoltaic Solution).
