PV技術の変遷 - PERCからTOPConへ

With the continuous development of solar photovoltaic technology, the traditional P-type cells are gradually approaching the theoretical limit of efficiency, while N-type cells have the advantages of high conversion efficiency, high bifaciality, low temperature coefficient, virtually no light decay, and good low-light effect, etc., and the much-anticipated N-type TOPCon module is becoming the new favourite of the photovoltaic industry.

1. Excellent weather resistance: JinenU modules meet the requirements of IEC standard tests, and have the ability to resist the risks of salt spray, ammonia, sand, dust, snail grain, and potential transmittance attenuation. And after 100% 4 times EL test, it ensures that the module has no hidden cracks.

2. Low temperature coefficient: The temperature coefficient of peak power (Pmax) of JinenU Solar's TOPCon modules is only -0.30%/°C, which is lower than that of PERC modules. This means that TOPCon modules perform better in high temperature environments with less power degradation.

3. High Bifacial Ratio - Low Radiation Performance: The bifacial ratio of JinenU Solar's bifacial TOPCon modules is up to 80%±5, which is higher than that of the general double glass PERC modules, which is 70%±5. In large-scale ground-based power station projects, the high bifacial ratio of TOPCon modules will significantly improve power generation efficiency. In areas with high ground reflectivity, the use of TOPCon modules with high double-sidedness will enable fuller use of reflected light and increase additional power generation.

4. Low attenuation rate: The linear power of TOPCon modules decreases by only 1% in the first year and 0.4% per year thereafter, which is lower than that of traditional PERC modules. Users will enjoy higher power generation benefits for a longer period of time and lower maintenance and replacement costs.

5. Non-destructive cutting technology: JinenU Solar TOPCon modules adopt non-destructive cutting technology, which effectively reduces cell damage problems and improves the reliability and stability of the modules. This enables TOPCon modules to maintain high performance stability in long-term operation and better adapt to various complex environments.

As a business model innovation, JinenU Solar focuses on customized module processing. With the development of PV market, JinenU Solar can help major PV companies and brands to briefly transfer production capacity during off-peak seasons and adapt to various market demand orders.
