Would these panels capture energy from the signal being radiated by my mobile phone? What about gamma rays? In other words, is a solar cell something that captures energy from photons and converts it into usable electricity? Or from some subset of photons?

These panels would not. The capture a subset.

  Is this a limit of photovoltaics or a design optimization? Or other?

    Most photovoltaics capture a narrow range which is why they stack different ones in this design.
