| Abstract: A microsystems-enabled multi-junction photovoltaic (MEM-PV) cell includes
a first photovoltaic cell having a first junction, the first photovoltaic
cell including a first semiconductor material employed to form the first
junction, the first semiconductor material having a first bandgap. The
MEM-PV cell also includes a second photovoltaic cell comprising a second
junction. The second photovoltaic cell comprises a second semiconductor
material employed to form the second junction, the second semiconductor
material having a second bandgap that is less than the first bandgap, the
second photovoltaic cell further comprising a first contact layer
disposed between the first junction of the first photovoltaic cell and
the second junction of the second photovoltaic cell, the first contact
layer composed of a third semiconductor material having a third bandgap,
the third bandgap being greater than or equal to the first bandgap. |
