Scientists follow the butterfly wing structure to develop high efficiency solar cells

The German Federal Ministry of education and Research (BMBF) recently announced that the Karlsruhe Institute of technology in the supported (KIT) researchers found that can efficiently enhance the solar absorption rate is a new way of light, through imitation of butterfly wing structure, development of high efficiency solar cell. The absorption rate of the new type of battery can be up to 207%.

In general, in the climate of Europe, the sun is much scattered and rarely vertically illuminates the solar panel. Optimization of optical capture is the cornerstone of energy conversion. The KIT researchers observed a swallowtail butterfly (Pachliopta Aristolochiae), found that the obvious features of the whole body is dark black, so the light absorption ability is very good, very suitable for their own heat gain. In particular, the wing surface of this butterfly is nanoscale, and its tiny cavity structure significantly increases the absorption of light on the smooth surface.

Simulating the nanostructure to produce solar cells, the light absorptivity can be increased by 97% when the light is irradiated vertically, and even 207% when the incident angle is 50 degrees. The butterfly nanoscale used in solar cells is realized by computer simulation optimization.
