Title:
SOLAR MODULE WITH PATTERNED COVER PLATE AND OPTICAL INTERFERENCE LAYER
Document Type and Number:
WIPO Patent Application WO/2020/020015
Kind Code:
A1
Abstract:
A solar module (1) comprises on the front a cover plate (10) with an outer surface (11) and an inner surface (13), wherein the outer surface (11) has at least one patterned region (15), on which an optical interference layer (16) for reflecting light within a predefined wavelength range is arranged, wherein the patterned region (15) has the following features: -perpendicular to the plane of the cover plate (10), a height profile having hills and valleys, wherein a mean height difference between the hills and valleys is at least 2μm, -at least 50% of the patterned region (15) is composed of segments (17) that are inclined relative to a plane of the cover plate (10), wherein, with reference to the plane of the cover plate (10), at least 20% of the segments have an inclination angle in the range from greater than 0° to a maximum of 15°, and at least 30% of the segments have an inclination angle in the range from greater than 15° to a maximum of 45°, wherein -the segments (17) are in each case flat and have a segment area of at least 1μm2, wherein in at least one zone of the patterned region (15), the segments (17) have in each case a mean roughness of less than 15% of a layer thickness of the optical interference layer (16) on the outer surface (11).
