The manufacturing of cast glass is a process developed already in the early 20th century. The glass ist casted in a continuous process directly after the melting oven. The imprinted glass is a clear, translucent flatglass, resulting from the continuous flow and the milling of the two rolls.
Schematic descritption of the milling process
The structure of the roll is crucial for the appeareance of the glass surface.
Against the background of elaborate Research and Development, purposeful surface structures have been created for solar applications. Depending on the structure type, it can be a helpful simplification of the lamination process (Albarino S). The surface structure is especially convincing when applied on the sunny side of a PV module. The deeply structured glasses Albarino P and Albarino G for example, have intelligent reflection characteristics that allows the installation of PV modules even close to airports (so called Anti-Glare effect)
Moreover, the light transmission and thus the efficiency of the final PV module can be improved significantly with a structured surface. Deeply textured surfaces not only reduce the reflection on the borderline Air/Glass, they are also capable of trapping and throwing back the light reflection of the laminated side of the glass and of the cell itself (Light-trapping effect).
