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