Amazed by Butterfly Wings

My new concept was on butterfly, after studying so much about them, I was so amazed with the structure of the wing.

Butterfly wing's color don't fade.
It's made of crystal nanostructures, called gyroid
The gyroid are made of chitin
The butterfly wing solar cells can convert 1% of the light energy that strikes them into electricity.
