Loss analysis of Low Bandgap (Ag,Cu)(In,Ga)Se2 Solar Cells for Tandem Applications
Francesco Lodola, Sevan Gharabeiki, Maximilian Krause +3
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 bandgap around 1…
Sodium induced beneficial effects in wide bandgap Cu(In,Ga)S2 solar cell with 15.7% efficiency
Arivazhagan Valluvar Oli, Kulwinder Kaur, Michele Melchiorre +10
This study underscores the pivotal role of sodium (Na) supply in optimizing the optoelectronic properties of wide bandgap (~1.6 eV) Cu(In,Ga)S2 (CIGS) thin film absorbers for high…
The effect of a band gap gradient on the radiative losses in the open circuit voltage of solar cells
Sevan Gharabeiki, Francesco Lodola, Tilly Schaaf +9
The radiative open circuit voltage loss in a solar cell occurs because the absorptance spectrum near the band gap shows gradual increase rather than sharp step function like transi…
