A hair brush with bristles pointed toward the sun would make an excellent target for adsorbing solar radiation. A little research to find the best black fiber might be worth the trouble.
As the ray of energy bounces back and forth among the bristles it is sure to find a home.
Some cone collectors
work on a similar scheme like a crabs eye lens for example.
If you ask how to get the energy back out again, I'll have to refer you to Dr. Von Braun as that is not my department.

Polar bear fur is actually a fiber-optic material. It might
appear to be white, and thus look reflective, but it also
collects quite a bit of light that is conducted directly to the
skin. |

It's a myth that it's a fibre-optic. It's not a fibre optic. |
