I've been thinking about this: The main problem with increasing PV output with mirrors is the penalty of additional heat.
I'm no expert, but PVs only convert certain wavelengths of light into electricity, and infrared (=heat) is not one of them.

Also, each materials reflects certain wavelengths better than others.

So, are there "mirrors" which reflect visible light but not heat? What materials could be used for this?
