Quite a bit of the EM spectrum is filtered out by the Earth's atmosphere, which means there's less incident solar energy per area on the ground that in space. There's more discussion of that topic here:
My multi-part question is:
Do solar panels designed to operate outside of Earth's atmosphere use those parts of the EM spectrum that don't reach the ground?
If they're NOT designed to capture those other parts of the spectrum, could they be?
Are there other known photovoltaic reactions in the infrared or UV that could in theory be exploited?
How much more electrical energy could be produced by doing so?
Does anybody have any online references with more detail about space vs ground solar panels?
