Canadian Solar announced 22.28 percent multi-crystalline cell conversion efficiency

Canadian Solar Inc. announced that the company has set a world record of 22.28 percent conversion efficiency for its p-type multi-crystalline P5 cell. The record high P5 cell efficiency was tested and certified by Fraunhofer ISE of Germany in April 2019. The record cell was fabricated by utilizing 157mm x 157mm P5 multi-crystalline wafers and other production-ready technologies such as selective emitter, silicon oxide passivation, multi-layer anti-reflection coating, aluminum oxide backside passivation, and advanced metallization. In addition, the MCCE (or Metal Catalyzed Chemical Etch) black silicon technology, originally developed by Canadian Solar, was also employed.
