NOTCH FILTER FOR TRIPLE JUNCTION SOLAR CELLS

摘要

A solar cell and method for producing same is disclosed. The solar cell includes a multijunction solar cell structure and a notch filter designed to reflect solar energy that does not contribute to the current output of the multijunction solar cell. By reflecting unused solar energy, the notch filter allows the solar cell to run cooler (and thus more efficiently) yet it still allows all junctions to fully realize their electrical current production capability.
