Abstract

An active window containing a Venetian blind made by N slats parallel to each other, wherein the slats comprise an electrochromic active material capable of varying their light throughput by controlling the transmittance and/or reflectance of the slats is described. The width of the slats being between 10% and 95% of a defined distance between two glass panes. The slats may be made of the electrochromic active material or the electrochromic active material may be layered onto the upper layer of the slats.

Claims

1. An active window comprising:

two glass panes spaced by a distance d, each of said glass panes having an area A comprised between 0.09 and 2 m²; and

a frame for the hermetic sealing of the active window,

wherein within said window is disposed a Venetian blind made by N slats parallel to each other, the width of said slats being comprised between 10% and 95% of said distance d,

wherein said slats comprise an electrochromic active material capable of varying their light throughput by controlling the transmittance and/or reflectance of the slats.

2. The active window according to claim 1, wherein the slats are made with the active material.

3. The active window according to claim 1, wherein the active material is layered onto the upper surface of the slats.

4. The active window according to claim 1, wherein the distance between adjacent slats is constant and comprised between 4 and 100 mm.

5. The active window according to claim 1, wherein said slats are tiltable.

6. The active window according to claim 5, wherein said tilting is achieved through a shape memory alloy material in the form of springs or wires, said shape memory alloy material being preferably nitinol.

7. The active window according to claim 1, wherein the window is filled with a gas chosen from dry air, nitrogen, argon, krypton at a pressure comprised between 900 and 1100 mbar.

8. The active window according to claim 1, wherein the window is evacuated at a pressure below 10⁻

3 mbar.

9. The active window according to claim 1, wherein the active material is embedded into a system connected to a photovoltaic element.

10. The active window according to claim 1, wherein the active material is integrated within a photovoltaic element.
