Method and apparatus for concentrating solar energy: click here to see abstract.

 

Permitting light transmission
without mirror-like coating.

TIR technology
(total internal reflection):
enabling back-reflection
(towards the sun)
of excessive sun energy.

The panel is made of double-glazed glass sandwiching
that looks like a cross section of a honeycomb.
The honeycomb is made of acrylic,
and inside each hexagonal cell is a silicon cell.
The hexagonal design serves to concentrate the sunlight by
2.5 times onto each cell.
