TRANSPARENT ELECTRODE WITH ASYMMETRIC LIGHT TRANSMISSION AND METHOD OF ITS MANUFACTURING Russian patent published in 2019 - IPC H01L21/00 G02F1/1343 

FIELD: electronic equipment.

SUBSTANCE: invention relates to the field of optoelectronic equipment and can be used for creation of touch screens, solar panels, the design of which includes elements which are simultaneously transparent to light and conductive electric current. Transparent electrode with asymmetric light transmission contains a transparent substrate made of a flexible material, on which there is a conductive layer of Al with ordered holes, coated with transparent spherical microparticles, which provides a wider field of application of the device. Aluminum film has holes of radius of 300–700 nm, arranged in the form of hexagonal grid, which provides close packing of focusing microspheres covering holes. Transparent spheres superimposed on the openings realize the effect of the photon nanojet and collimate the optical radiation incident on them in the beams passing through the holes with diameter smaller than the wavelength of the incident radiation and considerably less than the sphere radius. System of holes in conducting layer, which corresponds to tight packing of microspheres, is created by microspheres photolithography. Close-packed monolayers of microspheres are applied by centrifugation.

EFFECT: wider field of use suitable for production on an industrial scale, including using rolled technologies, and solving the problem of broadening the functionality of the transparent electrode.
