Preparing surface coating with microstructure lattice on transparent carrier element, by applying precursor with transparent conductive oxide on carrier element by wet-chemical method, and drying the precursor with the conductive oxide

摘要

The method comprises applying a precursor with a transparent conductive oxide (TCO) on a carrier element (2) by a wet-chemical method, drying the precursor with the TCO, irradiating the applied precursor with a laser along a pattern, where the precursor is sintered along the pattern, and removing a non-sintered precursor with the TCO from the carrier element using a solvent so that the sintered precursor remains on the carrier element and forms a microstructure lattice (10). The wet-chemical method is a sol gel method. The precursor contains a metal salt.

The wet-chemical method is a sol gel method. The precursor contains a metal salt, and is dissolved in the solvent with an organic complexing agent. The precursor with the TCO and the laser is coordinated to each other so that the precursor with the TCO strongly absorbs an emitted wavelength (248 nm) of the laser. The laser is an excimer laser. An independent claim is included for a solar collector.
