Abstract

Systems and methods for transparent materials implementing effectively transparent conductors in accordance with various embodiments of the invention are illustrated. One embodiment includes a window including a first transparent layer of transparent material having a first surface and a second surface, a first plurality of triangular conductors in optical communication with the first transparent layer of glass, wherein each of the first plurality of triangular conductors includes a base side that is parallel to the first surface of the first transparent layer of glass and wherein the first plurality of triangular conductors is configured to redirect a portion of incident light, wherein the portion of incident light travels through both the first surface and the second surface of the first transparent layer of glass.

Claims (18)

1. A window comprising:

a first transparent layer of glass having a first surface and a second surface;

a first plurality of triangular conductors in optical communication with the first transparent layer of glass;

wherein each of the first plurality of triangular conductors comprises a base side that is parallel to the first surface of the first transparent layer of glass;

wherein the first plurality of triangular conductors is configured to redirect a portion of incident light, wherein the portion of incident light travels through both the first surface and the second surface of the first transparent layer of glass;

wherein the first plurality of triangular contacts is embedded in a first surface of a superstrate layer, wherein the superstrate layer comprises a second surface opposite the first surface of the superstrate layer; and

wherein a plurality of nanostructures disposes on the second surface of the superstrate layer.

2. The window of claim 1 , wherein the first surface of the superstrate layer is disposed adjacent to one of the surfaces of the first transparent layer of glass.

3. The window of claim 1 , further comprising a layer of transparent conductive oxide disposed adjacent to the first surface of the superstrate layer.

4. The window of claim 1 , wherein the superstrate layer comprises a material selected from the group consisting of: ethylene-vinyl acetate, polyurethane, poly-methyl methacrylate, polydimethylsiloxane, ethylene chlorotrifluoroethylene, and ethylene tetrafluoroethylene.

5. The window of claim 1 , further comprising an active absorber layer, wherein the first plurality of triangular contacts is configured to redirect the portion of incident light to towards the active absorber layer.

6. The window of claim 1 , further comprising a second transparent layer of glass having a first surface and a second surface, wherein the portion of incident light travels through both the first surface and the second surface of the second transparent layer of glass.

7. The window of claim 6 , wherein the first and second transparent layers of glass form a sealed cell, wherein the sealed cell comprises argon gas.

8. The window of claim 1 , further comprising a plurality of nanostructures disposed on one of the surfaces of the first transparent layer of glass.

9. The window of claim 1 , wherein the first plurality of triangular contacts comprises a metallic nanoparticle ink selected from the group consisting of: silver nanoparticle ink and copper nanoparticle ink.

10. The window of claim 1 , wherein one of the first plurality of triangular contacts comprises an aspect ratio that is different than an aspect ratio of another of the first plurality of triangular contacts.

11. The window of claim 1 , wherein the first plurality of triangular contacts are patterned in a parallel configuration, wherein a pitch between two of the first plurality of triangular contacts is different than a pitch between another two of the first plurality of triangular contacts.

12. The window of claim 1 , further comprising a set of electrodes electrically coupled to the first plurality of triangular contacts.
