Abstract

We investigate the interface of InAs/GaSb as a device structure to enhance tunneling between subcells in multi-junction solar cells. Simulation is performed to study the conduction and valence band profile at the interfaces and determine the size of the tunneling barriers for charge carriers. An InAs/GaSb tunnel diode is also grown and fabricated. The conduction properties of this tunnel diode show good ohmic behavior and low contact resistance.
