Abstract
A glazing unit is provided for producing an aesthetically pleasing effect, comprising or consisting of at least one pane, said pane having a first structured surface to which a three-dimensional photonic structure is applied and the average refractive index of the photonic structure being higher than approximately 1.6 or higher than approximately 1.8 or higher than approximately 1.95. A method of producing such a glazing unit and the use thereof is also provided.
Claims19
A glazing unit for an esthetically pleasing effect, the glazing unit comprising:
- a glass, wherein the glass has a first surface having a RMS roughness of 30 nm to 100 μm to which a photonic layer structure is applied which is configured to reflect a first partial spectrum of incident electromagnetic radiation and to transmit a second partial spectrum of incident electromagnetic radiation, the reflected proportion corresponding to a higher harmonic and being in the visible spectral range, wherein the photonic layer structure includes a Bragg filter comprising a plurality of layers, each layer having a thickness that is in a range from 120 nm up to 240 nm, wherein the glazing unit as part of a photovoltaic module has a reflection loss of less than 12%.
A method for producing a glazing unit for an esthetically pleasing effect, the unit comprising a photonic layer structure and a glass, the method comprising:
- providing the glass,
- forming a first surface having a RMS roughness of 30 nm to 100 μm on the glass, and
- applying the photonic layer structure to the first surface so that the first surface is configured to reflect a first partial spectrum of incident electromagnetic radiation and to transmit a second partial spectrum of incident electromagnetic radiation, the reflected proportion corresponding to a higher harmonic and being in the visible spectral range, the photonic layer structure including a Bragg filter comprising a plurality of layers, each layer having a thickness that is in a range from 120 nm up to 240 nm, wherein the glazing unit as part of a photovoltaic module has a reflection loss of less than 12%.
