Multijunction Photovoltaic Cell - Description - Increasing Efficiency
... only exists if one considers a material with a single bandgap ... If you build a cell with multiple bandgaps, and tune each one to a different wavelength, then it is possible to capture the energy that would otherwise be lost through relaxation, without sacrificing ... For instance, if one had a cell with two bandgaps in it, one tuned to red light and the other to green, then the extra energy in green, cyan and blue light would be ...
