III-V semiconductor multi-junction solar cells are well suited for concentrating systems because their high power conversion efficiency can remain good not only under a single solar illumination, but also under the concentration of 1000 suns.

Crystal structure: The various combinations of III-V semiconductors have similar crystal structures and ideal properties for solar cells, including long exciton diffusion lengths, carrier mobility, and compatible absorption spectra.

Multi-junction solar cells structure is multi-layers of single-junction solar cells on top of each other. Band gap of the materials form the top to the bottom going to be smaller and smaller. It allows to absorbs and converts the photons that have energies greater than the bandgap of that layer and less than the bandgap of the higher layer.
When sunlight hits the n-type layer, electrons flow from that section to the second and create an electrical current that can be captured and used for power. This type of solar cell is known as a single-junction solar cell, as it has one single boundary/junction between the n-type and p-type layers, known as a p-n junction.
Multi-junction solar cells consist of some single-junction solar cells stacked upon each other, so that each layer going from the top to the bottom has a smaller bandgap than the previous, and so it absorbs and converts the photons that have energies greater than the bandgap of that layer and less than the bandgap of the higher layer .
The output current of the multijunction solar cell is limited to the smallest of the currents produced by any of the individual junctions. If this is the case, the currents through each of the subcells are constrained to have the same value.
The improvement in efficiency on going from one to two or three band gaps is considerable, but, as Table 2 shows, the returns diminish as more junctions are added, so the practicality of the solar cell with more than four or five junctions is doubtful.
Instead, materials like gallium indium phosphide (GaInP), indium gallium arsenide (InGaAs), and germanium (Ge) are used to create separate layers of semiconductors that all respond to different wavelengths of incoming sunlight. Layers in a multi-junction solar cell. Source:
