Canadian Solar Inc. achieves 21.1% cell efficiency using new advanced technical concept based on Merck’s isishape® and RENA’s InClean technology
Merck announced today that the Selective Emitter concept based on Merck's and RENA's new advanced technology is being implemented in Canadian Solar Inc.'s (CSI) high-efficiency solar cell production. With this, CSI achieved 21.1% cell efficiency according to in-house testing.
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).
