Inorganic‐Nanoparticle‐Based Super‐Hydrophobic Colored Coatings for Sustainable Building‐Integrated Photovoltaics

Building-integrated photovoltaics (BIPVs) have gained significant attention by promising renewable electricity without concerns of additional space, environmental damage, and maintenance problems. However, silicon-based BIPVs generally limit aesthetic appearance due to their monotonous dark blue modules. In addition, maintaining performance is challenging because BIPV modules are easily contaminated particulate matter, hindering practical applicability. this study, a solution-based process functional nanoparticles (NPs) employed fabricate large-area colored films with self-cleaning properties. The stable robust NPs comprising inorganic-based fluorinated silica (F-SiO2) silica-coated gold ([email protected]2) synthesized for integration, respectively. then self-assembled into hierarchical structure the aid silicone-based binder over large area (1 m2) using customized convective-assembly equipment, resulting in tunable hydrophobic super-hydrophobic surfaces. Finally, they applied on front glass 3 kW solar system constant 1 year, energy efficiency ≈89.5%. Moreover, show excellent stability after damp heat (85 °C/85%) accelerated weathering tests. Hence, expected be utilized as film sustainable BIPVs.
