The multijunction solar cells can be found in two configurations: in parallel or in series/tandem . As for thin-film solar cells with heterojunctions, for enhanced performances all layers should have similar crystalline structures/lattice constants. Otherwise, the discontinuities in the lattice constants lead to defects or dislocations at the interface, which are preferred recombination sites., which are preferred recombination sites.
, 1. are solar cells with multiple p–n junctions made of different semiconductor materials. Each material's p-n junction will produce electric current in response to different wavelengths of light.
