Recently, Taizhou Zhonglai Optoelectronics Technology Co., Ltd. received an IBC battery test report from the Solar Photovoltaic Power Generation System and the Wind Power System Quality Inspection Center of the Chinese Academy of Sciences. The report shows that the conversion efficiency of the N-type IBC battery with the M2 size is 23.04%. This means that Zhonglai Optoelectronics has made major breakthroughs in the industrial production of IBC batteries through continuous technological innovation, and it is in the leading position in the IBC battery conversion efficiency for mass production.
The double-sided battery with N-type IBC structure is the battery structure with the highest conversion efficiency in the N-type battery. The front surface of the battery has no grid lines, and the optical trapping effect on the front surface and the surface passivation and battery metallization are on the two surfaces of the battery. Therefore, the mutual constraints between them can not be considered, which greatly expands the optimization space for the optical and electrical performance of IBC batteries, and the battery conversion efficiency has also been greatly improved.
