Abstract: In an insulating glazing unit including at least one curved rigid pane, another rigid pane and a spacer frame joining the two panes together by an impermeable adhesive, a space is created between the panes. The spacer frame has a variable cross-section over its length, looking in the direction of its longitudinal extension, in the region of the joining between the curved rigid pane and the other rigid pane. The spacer frame, in at least in the aforementioned region, includes a plastically deformed elastomer material when the two rigid panes are mutually pressed together.

Abstract: A solar cell, having a silicon layer which has a dopant of a first dopant type, a front designed for the light coupling, and a rear. The silicon layer has a doped base layer, at least one textured layer and a metal layer being arranged on the rear of the silicon layer, optionally on additional intermediate layers, and the textured layer including a rear texture in at least a section thereof which rear texture is designed as an optical diffraction structure. At least one textured intermediate structure (3, 23, 33) is arranged between the textured layer (2, 22, 32) and the metal layer (4, 24, 34), the metal layer (4, 24, 34) being connected to the textured layer (2, 22, 32) and/or to the base layer (1, 21, 31) in an electrically conducting manner. The textured intermediate structure (3, 23, 33) is substantially transparent at least in the wavelength range of 800 nm to 1100 nm and has a refractive index n smaller than the refractive index of the textured layer in at least this wavelength range.

Abstract: A solar cell, including a silicon substrate (1), a front side (2) designed for coupling light, and a rear side (3) is provided. It is essential that the front side, at least in a partial region, has a front side texture, which along a spatial direction A is periodic, the period length being greater than 1 ?m, and that the rear side, at least in a partial region, has a rear side texture, which along a spatial direction B is periodic, with the period length being smaller than 1 ?m. The spatial direction A is disposed at an 80° to 100° angle to the spatial direction B.

Abstract: A glass pane is provided. A marking field that includes an uneven surface structure is located on a limited area of a smooth side surface of the glass pane. The limited area is smaller than a total area of the side surface of the glass pane, and the uneven surface structure is more rough than portions of the side surface of the glass pane that are outside of the limited area of the side surface of the glass pane. A marking layer is located on the marking field so as to create an intimate adhesive bond between the marking layer and the marking field. The marking layer includes a color containing a thermochromic pigment that visually indicates that a heat treatment has been carried out on the glass pane by being irreversibly modified at a temperature at which the heat treatment is conducted.
