Solar cell efficiency case [3]

In May 2018, the conversion rate of high-efficiency p-type monocrystalline cells reached 23.95%, breaking a world record, and was recognized by the Chinese Academy of Sciences Solar Power Plant and Wind Turbine Quality Inspection Center.

        High-efficiency battery technology is a high-dose, low-defect p-type single crystal silicon wafer developed independently of crystallography. It has a selective emitter and a comprehensive process optimization of silicon oxide passivation layer. It is expected to be used for reverse passivation. Combine.         The conversion efficiency is as high as 23.95%. Compared with metallization, it adopts advanced electrode design and chooses new screen printing paste. Reduce the series resistance, reduce the possibility of metal/silicon interface recombination, and significantly increase the battery fill rate.

        Prior to this, the conversion efficiency of p-type single crystal cells was 23.45% of that of crystal cells. Crystallography broke the world record in the field of p-type polycrystalline solar cell conversion and monocrystalline. The cell efficiency (22.04%) in October uses high-quality industrial boron-doped polysilicon chips and light capture and passivation technology. Advanced technologies such as light attenuation resistance are integrated into the Perc technology framework. The cell efficiency reached 22.04%, and the result was checked by the test laboratory of the Fraunhofer ISE Solar Energy System Institute in Germany.
        It is in a leading position in the operating records of single cell and polycrystalline cells, not only as a component supplier, but also showing strong technical capabilities. , The new battery production and production line adjustments have been announced. The fastest production and mass production of new batteries will make products more competitive and have a huge impact in the industry.
