Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se 2 Solar Cells for Tandem Applications

ABSTRACT Tandem solar cells can better harness the energy of the solar spectrum. Chalcopyrite solar cells have drawn attention, being the only highly efficient devices with a bandgap around 1.0 eV, suitable for bottom cells. In the quest for better efficiencies, we conduct a comp...
