Nano-enhanced solar cells incorporating III-V quantum wells or quantum dots have the potential to revolutionize the performance of photovoltaic devices. Extended spectral response characteristics have been widely demonstrated in both quantum well and quantum dot solar cells using a variety of different III-V materials. To fully leverage the increased spectral response of nano-enhanced solar cells, new device designs are discussed that can both maximize the current generating capability of the limited volume of narrow band-gap material and minimize the unwanted carrier recombination that degrades the voltage output.
