Couldn't one build a dielectric mirror onto the surface of the panel to selectively reflect those frequencies that aren't converted well, to avoid the thermal load of absorbing them? Is the issue that dielectric mirrors are too fragile?
- jacquesm 5y agoNo, the problem is that your dielectric mirror would have to be a perfect reflector for one set of wavelengths and a perfect passthrough for the remainder. In practice though it will always be gradients so you'll end up reflecting some of what you want and passing some of what you don't want.
