While perovskite technology stands out as the most efficient among photovoltaic (PV) panels, the prevailing choice in today's solar panels is monocrystalline. Within the domain of monocrystalline cells, N-type technology is anticipated to become the dominant solution in the market by 2023. With the advent of DeepBlue 4.0, JA Solar has transitioned to N-Type technology following the introduction of DeepBlue 3.0. The remarkable increase in efficiency to 22.4% was achieved through the incorporation of advanced N-type cells and innovative Gapless Flexible Interconnection (GFI) technologies.
This technological leap has propelled module power to an impressive 635W. Leveraging GFI technology, module power can be augmented by over 5 watts, accompanied by an increase in module efficiency by at least 0.2%. Noteworthy enhancements have been made in the degradation factor, with first-year degradation less than 1% and annual degradation over 30 years held below 0.4%. The temperature coefficient has been reduced to -0.30%/°C, showcasing minimal temperature-dependent power loss (ΔPmax/ ΔT). The overall power loss is a mere 2%, significantly surpassing the rigorous IEC standards. Moreover, the Bifacial Benefits have been elevated to an impressive 80%.
Below you will find the main products using all the above-mentioned technologies.
