The German Federal Ministry of Education and Research recently announced that researchers at the Karlsruhe Institute of Technology (KIT) funded by the German Federal Ministry of Education and Research have discovered a new way to efficiently increase the absorptivity of solar cells by developing efficient solar cells by emulating the butterfly wing structure. Absorbance of the battery can be increased by up to 207%.
In general, under the weather conditions in Europe, most of the sunlight is scattered and rarely shines vertically on the solar panel. Optimized light capture becomes the cornerstone of energy conversion. KIT's researchers observed a species of Pachliopta aristolochiae and found it. The distinctive feature is that the whole body is dark black, so it absorbs light very well and is very suitable for obtaining heat for itself. In particular, the wing surface of the butterfly is nanostructured. Its tiny hollow structure significantly increases the absorption of light over a smooth surface. .
Emulating this nanostructure to produce solar cells, the light absorption rate can be increased by 97% when the light is perpendicularly irradiated, and can even reach 207% when the incident angle is 50 degrees. The butterfly nanostructure used for the solar cell is realized through computer simulation optimization. of.
