International ClassesH01L 031/042H01L 031/048 AbstractThe present invention discloses a dust-proof and weather resistant photovoltaic module, including (a) a front substrate of light transmittable safety glass plate, wherein a photo-catalyst composition is applied to the safety glass plate; (b) a back substrate of weather resistant polyester polymer; and (c) a photosensitizer including electrical circuit copper foils and polymeric enclosing material (EVA) which is located between the front substrate and the back substrate. The method for fabricating a front substrate of a photovoltaic module includes applying a photo-catalyst composition onto a safety glass plate; evaporating the photo-catalyst composition to a gel; and seating the gel to Rutile titanium dioxide. The photo-catalyst composition includes a metal oxide, an acid regent and a surfactant.Field of SearchPanel or arrayContact, coating, or surface geometry Cadmium containing Copper, lead, or zinc containing Cells Packaging (e.g., with mounting, encapsulating, etc.) or treatment of packaged semiconductor Having additional optical element (e.g., optical fiber, etc.) Including integrally formed optical element (e.g., reflective layer, luminescent layer, etc.) Chalcogen (i.e., oxygen (O), sulfur (S), selenium (Se), tellurium (Te)) containing Polycrystalline semiconductor Contact formation (i.e., metallization) Photoelectric Glass Spraying Immersion Metal or metallic compound containing coating With optical shield or mask means With housing or encapsulation | |
