Scientists Developed Efficient Solar Cells Modeled After Butterfly Wings

- Mar 12, 2018-

German federal diligence (BMBF) recently announced that in karlsruhe institute of technology (KIT) of funding, the researchers found that new method can effectively improve the solar cell absorption, then the structure of butterfly wings, can develop the most efficient solar cells.The absorbance of new batteries can reach up to 207%.

Normally, in Europe's climate, the sun's rays are mostly scattered and are rarely seen vertically on solar panels.Optimizing light capture becomes the cornerstone of energy conversion.The KIT researchers looked at Pachliopta aristolochiae, and found that it was characterized by dark black, so absorbability was good, and it was good for getting heat for itself.In particular, the surface of the butterfly's wings is nano-structure, and its tiny, hollow structure significantly increases the absorption range of light.

Emulating the nanostructure to produce solar cells, the absorbance can be increased by 97 per cent when the light is vertical, and even 207 per cent when the incident Angle is 50.The butterfly nanostructures used in solar cells are optimized by computer simulation.
