An interdisciplinary team of researchers at McCormick Northwestern Engineering have discovered that Blu-ray discs could also help improve solar cell performance. These discs have a quasi-random pattern for data storage. When this pattern is transferred to solar cells it can increase the light absorption capacity of these cells.
When compared to DVDs, Blu-ray discs possess a higher data storage density. This is due to its quasi-random pattern that it uses for data storage. The research team transferred this pattern on to the surface of solar cells.
