May 28 (Renewables Now) - Canadian Solar Inc (NASDAQ:CSIQ) announced on Tuesday it has achieved a world record conversion efficiency of 22.28% for its p-type multi-crystalline P5 cell.

The Fraunhofer Institute for Solar Energy Systems ISE (Fraunhofer ISE) of Germany tested and certified the record high P5 cell efficiency last month, Canadian Solar said in a statement.

To fabricate the specific cell, the solar power company used 157mm x 157 mm P5 multi-crystalline wafers along with production-ready technologies like selective emitter, silicon oxide passivation, multi-layer anti-reflection coating, aluminum oxide backside passivation and advanced metallisation, plus the MCCE (Metal Catalyzed Chemical Etch) black silicon technology.

Also today, competitor Trina Solar said it had achieved a record-high 24.58% conversion efficiency for an n-type mono-crystalline silicon (c-Si) i-TOPCon solar cell.
