High Voltage Multijunction Photovoltaic Devices: Current Matching and the Characterization of Low Bandgap Material Germanium Tin

A next step in the energy transition is to produce green fuels from sunlight. One way to achieve this is via high voltage photovoltaic (PV) devices which can directly drive electrolysis reactions to produce hydrogen or other chemical fuels. Group IV based multijunction (MJ) PV devices are a candidate to function as these high voltage devices.<br...
