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…

Improved sequentially processed Cu(In,Ga)(S,Se)2 by Ag alloying
Aubin JC. M. Prot, Michele Melchiorre, Tilly Schaaf +10
Alloying small quantities of silver into Cu(In,Ga)Se2 was shown to improve the efficiency for wide and low band gap solar cells. We study low band gap industrial Cu(In,Ga)(S,Se)2 a…
