 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.  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 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. +From the little info publicly available, 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.
