A new approach to P-doping and the observation of efficiency enhancement in InP/InGaAs quantum well solar cells

The authors report on lattice matched InP/In/sub x/Ga/sub 1-x/As multiple quantum well solar cells (QWSCs). An alternative method of p-doping is used, which allows the dopant to diffuse from a highly doped InGaAs cap into an underlying InP layer which has no deliberate doping. They discuss an import...

description The authors report on lattice matched InP/In/sub x/Ga/sub 1-x/As multiple quantum well solar cells (QWSCs).
