Windows with multiple panes

Abstract

A window is provided with a first pane (2; 3) and a second pane (3; 20) spaced apart from it, wherein the first pane (2) has a first side (4) facing the second pane (3) and the second pane (3) has a second side (5) facing the first pane (2), wherein a cavity (6; 22) is located between the two mutually facing sides (4, 5), which is closed by means of an edge seal (7) and which is filled with a gaseous medium, wherein the two panes (2, 3; 20) are transparent to radiation from the visible wavelength range and radiation from the infrared range, wherein the edge seal (7; 21) is a photovoltaic cell (8;25) has an IR radiation with a predetermined wavelength from the infrared range that converts into electrical energy, wherein the first disk (2) has a first hologram (10) and the second disk (3) has a second hologram (11), wherein the two holograms (10, 11) are designed such that the IR radiation (L1), which has predetermined wavelengths and which strikes the first disk (2) at a predetermined first angle of incidence (α1), undergoes a first deflection at one of the two holograms (10, 11) to the other of the two holograms (10, 11) such that the deflected IR radiation (L2) strikes the other of the two holograms (10, 11) at a second angle of incidence (α3) which is greater than the first angle of incidence (α1) and is deflected by it at a first angle of reflection (β3) which is greater than the second angle of incidence (α3) enters the cavity (6) and propagates within it to the photovoltaic cell (8; 25).;
