JinkoSolar hits new n-type monocrystalline silicon solar cell efficiency record



/*** Advertisement ***/

JinkoSolar Holding Co. announced a record high efficiency of 24.2% was achieved by its large-area N-type TOPCon monocrystalline silicon solar cell. Testing was conducted by the Photovoltaic and Wind Power Systems Quality Test Center at the Chinese Academy of Sciences (CAS).

The large-area N-Type cell features JinkoSolar’s HOT cell design, which is based on tunnel oxide passivating contact technology. JinkoSolar’s high quality N-type wafer, selective doping technology, and advanced fine-line printing technology allow the Company to achieve 24.2% cell efficiency across its entire product chain. The world PV module power record of 387.6W for N-type half-cell module (60P) was fabricated using JinkoSolar’s HOT cell design.
