In this paper the researchers present a thorough subcell diagnosis methodology to reveal deep insights into the practical efficiency limitations of state-of-the-art perovskite/silicon tandem PVs.

Setfos was used by the researchers to simulate band diagrams with either aligned energy levels or energy offsets in the perovskite subcell.
