摘要： One embodiment can provide a solar roof tile. The solar roof tile can include a front cover, a back cover, one or more photovoltaic structures positioned between the front cover and the back cover, and a band-stop optical filter positioned between the front cover and the photovoltaic structures. The band-stop optical filter is configured to block light within a predetermined spectral range, thereby preventing the light from reflecting off surfaces of the photovoltaic structures to exit the solar roof tile.

摘要： Micro-structures and directional and multi-directional coatings for uniformly colored and directionally colored photovoltaic modules and roof tiles are described. The photovoltaic roof tiles include a glass cover with texture of a micro scale on a first side, and one or more layers of a transparent material adjoining the first side of the textured glass configured to reflect light of a color. A glass cover can have texture on a first side and a layer of sphere shaped metal nanoparticles adjoining the first side of the textured glass cover. Directionally colored solar modules can include a textured glass cover with texture on a first side and a coating layer covering one or more facets of the texture on the first side of the glass cover. The coating layer may be deposited by coating the textured glass cover in one or more directions.

摘要： Treatments are provided to strengthen adhesion of an optical filter layer in a photovoltaic (PV) module to an encapsulant layer, or generally, between inorganic materials and organic polymers. The embodiments disclosed herein can provide five or more times the adhesive forces of untreated encapsulant-filter interfaces. As a result, the system can enhance long-term reliability of PV modules by reducing interface surface charges and dangling bonds and reducing gaps and cracks, thereby preventing moisture, impurities, and particles from entering the interface. The treated optical filter layer can result in a surface modification. In some embodiments, treating the optical filter layer includes applying a chemical treatment such as an acid or alkaline wash, and/or ultrasonic cleaning.
