China-headquartered, Trinasolar announced that its industrial 210×182 sq mm n-type bifacial i-TOPCon solar cell achieved a record efficiency of 25.9%, verified by ISFH CalTeC in Germany. This represents the 27th instance in which the company has set or surpassed an efficiency record for solar cells or modules. The cell utilizes a rectangle wafer design with an n-type phosphorus-doped Cz silicon substrate. Key technologies, such as tunnel oxide passivating contact, boron-doped emitter, advanced light-trapping, and fine line printing, were used to reach this efficiency level. This new record surpasses the previous one held by Fraunhofer ISE since 2017.
