Perovskite-based tandems have attracted significant interest as a new type of high-efficiency solar cells, surpassing current technologies like single-junction Si solar cells. Tandem cells, which consist of multiple light-absorbing layers with different bandgap energies, are theoretically expected to exceed the Shockley–Queisser limit by effectively utilizing the incident light and minimizing thermalization losses.
