To increase the efficiency of a solar panel by 22%, the researchers at Northwestern bought a copy of Police Story 3: Supercop on Blu-ray; removed the top plastic layer, exposing the recording medium beneath; cast a mold of the quasi-random pattern; and then used the mold to create a photovoltaic cell with the same pattern. As you can see in the image above, this process actually makes the nanopatterned solar cell have the same iridescence as a Blu-ray disc. The end result is a solar panel that has a quantum efficiency of around 40% — up about 22% from the non-patterned solar panel. *This content was curated by @CleanEnergy on #Tsu.
