FIELD: solar energy technologies.
SUBSTANCE: invention relates to a multi-junction solar cell. Essence: multi-junction solar cell (MJ) in the form of a stack, which includes a stack (ST) consisting of the lowest sub-element (C1), at least one middle sub-element (C2) and the topmost sub-element (C3), each of the sub-elements (C1, C2, C3) has an emitter (E1, E2, E3) and a base (B1, B2, B3), at least the topmost sub-element (C3) consists of III-V-semiconductor material or includes a III-V-semiconductor material and the emitter (E3) of the topmost sub-element (C3) includes a superlattice (SL).
EFFECT: extension of the alternative energy source range.
