Afaik the radiative cooling element should not point to the sun for good performance. On the other hand you want to have your solar cell pointing to the sun. So at least one of them doesn't perform well.
Eg. on a building with tilted roof (prevalent in Middle Europe ) one would like to mount the former on the north side and the latter on the south side for good performance. Unfortunately the article does make no mention of it.

- satya71 7y agoIt's been a while since I brushed up my physics, but that's not how it used to work, IIRC. Every body (in the physics sense) radiates heat, and that's independent of the incident energy. When the incident energy is more than the radiated energy, there is net energy transfer into the body leading to temperature rise.
