Abstract :
Injection effects can be effectively utilized in multijunction solar cells to provide new device design rules and higher efficiency cells. A multijunction cell with multiple layers can take advantage of injection effects to de-couple the thickness of each individual layer from the overall series resistance. This allows improved collection efficiency in the presence of high surface recombination, reduced series resistance, and reduced metal shadowing losses
