Abstract

The commonly used CdS/i-ZnO buffer system in Cu(In,Ga)Se2 (CIGS) thin-film solar cells is substituted either by Zn(O,S)/(Zn,Mg)O or (Cd,Zn)S/(Zn,Mg)O and investigated by electro-optical simulations. We considered different (Zn,Mg)O compositions and thicknesses to find the combinations giving the highest power conversion efficiencies. Similarly, we examine the effect of variations of the Zn mole fraction in (Cd,Zn)S for the (Cd,Zn)S/Zn0.83Mg0.17O system on the CIGS solar cell’s figures of merit.
