On October 25, 2017, JinkoSolar announced that it has set a world record in a number of its battery components technologies. After being verified by the Chinese Academy of Sciences Testing Laboratory, its P-type single crystal PERC battery has achieved a high world-record conversion efficiency of 22.78%. This is the world record of breaking the efficiency of single crystal PERC cell after JinkoSolar's new record of updating the efficiency of P-type polycrystalline PERC cell by 22.04% this year.After verification by TUV Rheinland Testing Laboratory, JinkoSolar P-type 60 Specification Sheet The power of the crystal module reaches 356.5W, the power of the P-type 60-size polycrystalline module reaches 347.6W, causing the photovoltaic industry's attention.
The P-type polycrystalline PERC solar cell achieved a substantial increase in efficiency, mainly based on several high-efficiency technology applications, including: high-performance P-type silicon substrate, body passivation technology, multilayer antireflection film technology, selective emitter Technology and fine grid metallization technology, etc. Among them, selective emitter (SE) and fine grid metallization technology greatly reduce the recombination loss on the cell surface, effectively improve the open circuit voltage and cell efficiency of the PERC cell, meanwhile the unique multi-layer Membrane passivation also contributes significantly to battery efficiency, while component power improvements are due to reduced internal electrical losses, the use of internal light, and improved cell efficiency.
Jingkang Energy CEO Chen Kangping commented: 'In 2018, Crystal Branch will continue to expand R & D investment, and these record-breaking R & D results of a pilot trial production, and quickly rolled out production capacity, to achieve large-scale, thus further reducing per watt Costs. Crystal Branch to become a technology research and development and advanced production processes are the highest volume of PV manufacturing enterprises.
