Canadian Solar's ELPS cell reaches 21.1% efficiency #solar

, a supplier of production systems for the wet chemical processing of substrates for photovoltaics and other applications, says that a selective emitter concept based on Merck and Rena's new technology is being implemented in Canadian Solar Inc.'s (CSI) high-efficiency solar cell production. With this technology, CSI has achieved 21.1% cell efficiency, based on in-house testing. The company reached the efficiency benchmark with monocrystalline solar cells using its proprietary ELPS (Efficient, Long-term Photovoltaic Solution) cell structure. Merck's isishape pastes ensure homogeneous and well-controllable etching, leading to an efficiency gain of 0.5%, according to the company. Rena adds that its cleaning technology, InClean, is specially designed for Merck's isishape. InClean is available as an upgrade for existing lines or can be integrated into a Rena InOxSide tool for ...
