Wave conversion technology enhanced HJT competition


Previously, the HJT supporters relied on the “three reductions” strategy, which aimed to reduce silver usage, fingers, and wafer thickness, while also optimizing transparent conducting oxides (TCO) and velvet. However, the introduction of phototransfer film technology has transformed this strategy into the “three reductions and one enhancement,” leveraging phototransfer film to boost power generation.

The emergence of phototransfer film technology has introduced a new avenue for enhancing the competition of HJT technology. Compared to the steady improvement in other aspects, phototransfer film provides an immediate and significant enhancement, which is also an innovation in terms of ideas. Just as laser doping has propelled TOPCon technology, phototransfer film could very well be the “last piece of the puzzle” for HJT technology.

light wavelength conversion film can absorb UV light and release visible light. So while sun light passes through light wavelength conversion film, the visible light and IR light of the sun light can pass through the film but the UV light of the sun light is converted to into blue light.

light wavelength conversion film can reduce HJT module degradation caused by UV rays, which accelerate aging. By integrating light wavelength conversion film, module power generation can be enhanced while simultaneously extending the overall lifespan of the modules. The advent of phototransfer film technology holds great significance as it offers a unique pathway to enhance module efficiency, especially when cell manufacturers encounter challenges in improving conversion rates.

In the dynamic and highly competitive technological arena, any breakthrough that enhances efficiency and reduces costs demands recognition. light wavelength conversion film has emerged as a particularly promising development for HJT technology, delivering a substantial gain of 10-12 watts per module. This boost translates to 1.5%-2% increase in energy generation. Akcome confirms an actual improvement of approximately 10 watts.
