Abstract:In Part I [Appl.
Opt. 59, 1018
(2020).APOPAI0003-693510.1364/AO.381246], we used a coupled
optoelectronic model to optimize a thin-film AlGaAs solar cell with a
graded-bandgap photon-absorbing layer and a periodically corrugated Ag
backreflector combined with localized ohmic Pd–Ge–Au backcontacts,
because both strategies help to improve the performance of AlGaAs
solar cells. However, the results in Part I were affected by a
normalization error, which came to light when w… Show more
