All beginnings now but this could all be important if it is possible to absorb a wide portion of the solar spectrum and then convert it to infra red without significant loss. The infra red radiation can then be turned directly into electrical energy which is usable.
Expect to see blue solar cells.
Blue matters as we can actually see it. It is the apparent background radiation associated with Dark Matter which makes it invisible unless you are sitting in a deep cave or mine and all lighting is turned out. Our sky is blue because all the other wavelengths that we can see are absorbed.
