JinkoSolar's N-type TOPCon technology has significant advantages in the PV industry, which are mainly reflected in the following aspects:
1. High efficiency and power generation gain
- High efficiency: JinkoSolar's N-type TOPCon modules are known for their high efficiency, enabling higher photoelectric conversion efficiency. According to the data, the conversion efficiency of Jinko's N-type TOPCon modules has been continuously improved, reaching the industry-leading level. The high efficiency means that the N-type TOPCon module can generate more electricity under the same lighting conditions, thereby increasing the overall power generation capacity of the PV system.
- Power generation gain: The N-type TOPCon technology achieves significant power generation gain by optimizing attenuation, reducing the temperature coefficient, and increasing the bifaciality. For example, Jinko's N-type TOPCon modules have a bifaciality rate 10-15 percentage points higher than that of P-type modules, which can achieve higher backside photoelectric conversion efficiency, thereby improving the overall power generation gain. In addition, N-type TOPCon modules have a better temperature coefficient and a first-year attenuation of as little as 1%, all of which contribute to the long-term power generation capacity and economic profitability of PV systems.
2. Technical compatibility and mass production capacity
- Technology compatibility: The N-type TOPCon technology is highly compatible with traditional PERC cell production lines, which allows JinkoSolar to achieve significant cost and time savings when upgrading and retrofitting production lines. At the same time, N-type TOPCon technology also has ultra-high photoelectric conversion efficiency, which is widely regarded as the preferred technology for the mass production of next-generation high-efficiency crystalline silicon cells.
- Mass production capabilities: JinkoSolar has made significant achievements in the mass production of N-type TOPCon technology. The company has successfully established a number of TOPCon cell factories with a scale of 8GW, becoming the first company to achieve large-scale mass production. This mass production capability not only satisfies the market demand for high-efficiency photovoltaic products, but also further strengthens JinkoSolar's leading position in the industry.
3. Product performance and reliability
- Product Performance: JinkoSolar's N-type TOPCon modules excel in several areas. For example, the mainstream version of its TigerNeo module has a power of 25-30W higher than that of the same version of PERC module. The temperature coefficient of N-type modules is better than that of PERC (0.75% increase in power generation on average). Bifaciality up to 85%, bringing significant power generation gain; and better low-light performance, etc. These performance advantages make N-type TOPCon modules more competitive in various photovoltaic application scenarios.
- Reliability: JinkoSolar's products also excel in terms of reliability. From 2016 to 2023, the company has been awarded the title of the best performer in the PVEL PV Module Reliability Scorecard for eight consecutive years, which fully demonstrates the reliability and stability of the company's products.
Fourth, technological innovation and R&D strength
- Technological innovation: JinkoSolar has invested significant resources in the research and development of N-type TOPCon technology, and has achieved remarkable results. The company's R&D team has gradually developed core process technologies such as hyperspectral response diffusion, ultra-thin tunneling layer, precision doped polysilicon and advanced metallization, and has completed the leap development of cell conversion efficiency while improving the cell structure. In addition, the company has also made an active layout in the continuous iteration of the technology process based on N-type TOPCon to ensure continuous technological advancement.
- R&D strength: JinkoSolar also excels in terms of the number of patents and scientific research achievements. As of April 30, 2023, JinkoSolar ranked second in the "Global Solar Cell Patent Rankings" in terms of patent volume. At the same time, the company's scientific research achievements have broken the world record 25 times. For example, JinkoSolar's N-type TOPCon large-area PV modules have a maximum conversion efficiency of 24.76%, setting a new record for the highest efficiency of modules in the world that has been certified by a third-party authority.
In summary, JinkoSolar's N-type TOPCon technology has significant advantages in terms of high efficiency, power generation gain, technology compatibility, mass production capacity, product performance, reliability, and technological innovation and R&D strength. These advantages have enabled JinkoSolar to maintain its leading position in the photovoltaic industry and lay a solid foundation for the company's future growth.
