Multi-junction photovoltaics (PVs) offer a promising avenue to optimize solar spectrum harvesting by mitigating inherent thermalization and transmission losses of single-junction devices, and they bear the potential to surpass the efficiency limit of single-junction solar cells (see Figure 1 A).
Solar cells are made of semiconductor material, typically silicon in crystalline solar cells. Traditionally, a solar cell has two layers: an n-type with a high concentration of electrons and a p-type with a relatively low concentration of electrons. When sunlight hits the n-type layer, electrons flow from that section to the second and create an electrical current that
