I remamber about the news of solar panels that worked by night. Indeed interesting, harvesting the heat and turning it electricity. Collect energy from the very hot asphalt sounds great.
But it could interfear with electromagnetic waves, like from cell phones.

Here's another one, capturing the blue part of the spectrum through re-radiation in a hydrogel:

This New 'Green' Antenna Could Double Solar Panel Efficiency

So — blue absorbing panels on the top, and infrared absorbing panels on the bottom.
