Running wave form extended states in charactering the photocurrent of multiple quantum well and superlattice structured GaAs/AlGaAs solar cells

Abstract

The numerical simulations of the contribution of GaAs/AlGaAs multiple quantum well and superlattice to photocurrent in solar cells are presented. Effects of thickness of barrier and period on the extended and localized states, photocurrent have been investigated. Running wave method of calculation on the extended states of the two structures are adopt and compared.
