摘要
An inverted metamorphic multijunction solar cell, and its method of fabrication, including an upper subcell, a middle subcell, and a lower subcell, including providing a first substrate for the epitaxial growth of semiconductor material; forming an upper first solar subcell on the substrate having a first bandgap; forming a middle second solar subcell over the first solar subcell having a second bandgap smaller than the first bandgap; forming a graded interlayer over the second subcell, the graded interlayer having a third bandgap greater than the second bandgap; and forming a lower third solar subcell over the graded interlayer having a fourth bandgap smaller than the second bandgap such that the third subcell is lattice mismatched with respect to the second subcell, wherein at least one of the solar subcells has heterojunction base-emitter layers.
