This structure employs uniformly fine velvety surfaces to minimise reflection, combined with an ultra-thin polysilicon layer utilising in-situ doping technology. This approach ultimately achieves outstanding performance characterised by high bifaciality and low attenuation.

Featuring a uniformly fine, low-reflectance velvety surface, it possesses an ultra-thin polysilicon layer with high double-sided efficiency and in-situ doping, exhibiting outstanding low-attenuation performance.

Rectangular cells have high power, low temperature coefficient, excellent low-light power generation, and user-friendly small size. They are suitable for distributed applications. The all-black modules make photovoltaic and architecture more beautiful.
