Nature is full of cutting-edge technology. Taking butterflies as an example, the researchers found tiny solar collectors on their wings. The solar collector's heat comes from the sun and can help warm the butterflies in cold weather.
Scientists at Shanghai Jiaotong University have found a way to replicate the solar collectors on the butterfly's wings and then transferred the device to a "dye-sensitized" battery. Solar collectors are like honeycombs, which help to disperse and absorb sunlight. Scientists believe that solar collectors on butterfly wings are much more efficient than traditional “dye-sensitized†batteries.
Imitation butterfly wings can be used to fabricate various optically active structures, such as optical diffusion or overlays, to maximize solar cell light absorption, or other types of devices. From the research and testing of this new material, the conclusions drawn indicate that this process may lead to more economical and efficient solar cells in the near future.
