-Now, a couple of researchers with interdisciplinary and seemingly non-related backgrounds have published the concept to apply a quasi-random nano-structure to a solar (PV) cell in order to increase the absorption of photons (decrease reflection) and reported an overall broadband absorption enhancement of that solar cell to be 21.8%, when a Blu-Ray land/pit pattern is applied. +Now, a couple of researchers with interdisciplinary and seemingly non-related backgrounds published the concept to apply a quasi-random nano-structure to a solar (PV) cell in order to increase the absorption of photons (decrease reflection) and reported an overall broadband absorption enhancement of that solar cell to be 21.8%, when a Blu-Ray land/pit pattern is applied. 
  
-From the little info what I could get, it seems they've just tried different materials for this approach and by sheer coincidence, as it turned out, Blu-Ray's compression algorithm (tested with Jackie Chan - Police Story 3: Supercop) creates a quasi-random array of lands and pits (0s and 1s) with feature sizes between 150 and 525 nm, which seems to work quite well for light-trapping (photon management) applications over the entire solar spectrum. +From the little info what I could get, it seems they've just tried different materials for this approach and discovered that Blu-Ray's compression algorithm (tested with Jackie Chan - Police Story 3: Supercop) creates a favorable quasi-random array of lands and pits (0s and 1s) with feature sizes between 150 and 525 nm, which seems to work quite well for light-trapping (photon management) applications over the entire solar spectrum.

 IMHO, it should be easy to use a real random number generator as a source, create some land/pit patterns following Blu-Ray specs (physical), run some tests and apply that to the production process. If it works, the sudden increase of convertible sustainable energy would be more than just considerable.  IMHO, it should be easy to use a real random number generator as a source, create some land/pit patterns following Blu-Ray specs (physical), run some tests and apply that to the production process.
