Chinese scientists at Shanghai Jiao Tong University have recently found that by replicating the structure of the wings of the Papilio Paris butterfly, they can enhance the efficiency of dye-sensitized solar cell (DSCs).
The species of Papilio Paris live in very cold conditions and sustain their body temperature by trapping sun’s heat using a special design pattern on their wings. On examination, researchers have found that the honeycomb-like microstructure of the wings is responsible for that, and they are now trying hard to translate it into a pattern at a micro level.
While the process is neither easy nor yet successful, this will help usher the stagnant technology of the dye-sensitized solar cells which are nowhere close to matching the efficiency of the photovoltaic solar cells. However, researchers are hoping that this new stroke of inspiration will soon change that.
Another step forward or just, money spent on ‘research’?
