Trina Solar Announces New Efficiency Record of 23.5% for Large-Area Interdigitated Back Contact Silicon Solar Cell

Trina Solar Limited (NYSE: TSL) (“Trina Solar” or the “Company”), a global leader in photovoltaic (PV) modules, solutions and services, today announced that its State Key Laboratory of PV Science and Technology of China has set a new world record of 23.5% for a high-efficiency silicon solar cell with an Interdigitated Back Contact (IBC) structure on a large-area 156×156 mm2 n-type mono-crystalline silicon (c-Si) wafer. This new record has been independently confirmed by the Japan Electrical Safety & Environment Technology Laboratories (JET), Yokohama, Japan.
The record-breaking n-type mono-crystalline silicon solar cell was fabricated with a process that integrates the advanced Interdigitated Back Contact structure with industrial low-cost processes. The best 156×156 mm2 solar cell fabricated entirely with a screen-printed process reached a total-area efficiency of 23.5%, which breaks the previous record of 22.94% for the same type of solar cell that was also established by the Company in May, 2014. …
