摘要

Light-absorption enhancement of silicon (Si)-based solar power systems ( i.e. , solar modules) is reported by employing a ultraviolet-curable polymer ( i.e. , NOA63) film integrated with a hierarchical structure (HS) consisting of nanonipples on micropyramids onto the PET cover as a protective antireflection (PAR) layer. The HS-patterns can be easily transferred from Si molds with the HS via poly-dimethylsiloxane stamps by soft lithography. The HS-NOA63 film increases the total and diffuse transmittances of the bare polyethylene terephthalate (PET), simultaneously, at wavelengths of 380–1100 nm, thus resulting in the reduced surface reflection ( i.e. , lower solar weighted reflectance ( R _(sw) ) of 6.1%) and the strong light scattering ( i.e. , much higher average haze ratio ( H _(avg) ) of 90.7%) compared to the bare PET ( i.e. , R _(sw) = 11.7% and H _(avg) = 6.9%). Consequently, the Si solar modules with the HS-NOA63 PAR layer of the PET cover exhibit a superior solar power generation in a wide incident angle range (0–70°) of solar irradiance, especially, showing a relative increment percentage of 6.3% in power conversion efficiency (PCE) at 0° ( i.e. , from PCE = 13.46 to 14.3%). Also, it has a superhydrophobic surface with a high water contact angle of 150°, which leads to a self-cleaning ability to protect Si solar modules from being polluted by water droplets and dust particles in outdoor applications.
