  • Patent number: 12040738
    Abstract: A glazing unit is provided for producing an aesthetically pleasing effect. The glazing unit may include at least one polymer with a first structured surface to which a photonic structure is applied. The surface can reflect a first partial spectrum of incident electromagnetic radiation, and can transmit a second partial spectrum of incident electromagnetic radiation. A reflected proportion corresponds to a higher harmonic and is in a visible spectral range.

  • Publication number: 20230387339
    Abstract: A multiple solar cell having at least two partial cells, at least being formed from a direct semiconductor, having an upper partial cell facing the light and a lower partial cell facing away from the light, an upper bandgap of the upper partial cell being greater than a lower bandgap of the lower partial cell, and an intermediate layer arranged on the lower partial cell side facing away from the light. An optical element including a lower mirror element is arranged on the intermediate layer side facing away from the light, and has a partial element having structural elements arranged in a lateral direction on the intermediate layer side facing away from the light. The structural elements have a mean spacing less than or equal to 1.3 times a spacing value that results from a ratio of a wavelength of the lower bandgap to a refractive index of the lower partial cell or the lower mirror element has a roughness having a root-mean-square value of less than 50 nm.

  • Publication number: 20150004331
    Abstract: A method for coating a substrate with an AlOx layer, in particular an Al2O3 layer, comprising the following method steps: (a) providing an inductively coupled plasma source (ICP source) having a reaction chamber and at least one RF inductor, (b) introducing an aluminium compound, preferably trimethylaluminium (TMA) into the ICP source, (c) introducing oxygen and/or an oxygen compound as reactive gas into the ICP source and inductively coupling of energy into the ICP source for forming a plasma, and (d) depositing the AlOx layer on the substrate. The invention also relates to a coating assembly for depositing thin layers on a substrate, in particular for carrying out the above method. The coating assembly comprises an inductively coupled plasma source (ICP) having a reaction chamber and at least one RF inductor, a substrate holder for arranging the substrate in the reaction chamber and channels for introducing the aluminium compound and a reactive gas in the ICP source.

  • Patent number: 6624584
    Abstract: The invention relates to a particle source, particularly an ion source for the production of excited particles in gaseous media. A dielectric, e.g., Kapton foil, is coated electrically conductively on both sides, and a voltage, preferably pulsed, is applied between the two coatings. A gas discharge is ignited in the gas through-flow by the voltage. Due to a pressure difference between the two sides of the foil, the gas expands from the high pressure side to the low pressure side, preferably in an ultrasonic expansion, whereby a directed, cold beam of excited particles or ions is produced.
