Transparent layer with anti-reflective texture

1. An assembly comprising:

a textured transparent panel and a photovoltaic cell or solar collector element configured to collect light, said panel being textured on at least one of its faces by a plurality of raised rhomboid geometrical features with respect to a general plane of said face, wherein each of the raised rhomboid geometrical features in the plurality has six faces, the textured face increasing light transmission of the panel and being placed on a side on which the light is received, a surface of said features each having at least a raised ridge line, wherein the rhomboid geometrical features form a rhomboid pattern that includes ridges, but not apex features.

2. The assembly of claim 1 wherein the raised ridge line is highest of any raised features on the panel.

3. The assembly as claimed in claim 1 , wherein the panel has touching features.

4. The assembly as claimed in claim 1 , wherein the panel has completely touching features.

5. The assembly as claimed in claim 1 , wherein a bulk of the panel essentially consists of materials whose linear absorption is less than 0.01 mm −1 within the spectrum ranging from 380 to 1200 nm.

6. The assembly as claimed in claim 5 , wherein the bulk of the panel essentially consists of a glass having a linear absorption of less than 0.008 mm −1 within the spectrum ranging from 380 to 1200 nm.

7. The assembly as claimed in claim 1 , wherein a distance between the panel and the element is less than 15 cm.

8. The assembly as claimed in claim 7 , wherein the distance between the panel and the element is less than 3 cm.

9. The assembly as claimed in claim 8 , wherein the distance between the panel and the element ranges from 0 to 10 mm.

10. The assembly as claimed in claim 9 , wherein the distance between the panel and the element ranges from 0 to 5 mm.
