Abstract
The present disclosure is directed to double junction tandem perovskite solar cells having a n/n interconnection layer comprising an ion-doped fullerene layer and a metal oxide layer. In certain embodiments, the metal oxide is SnO(0<x<1). The ion-doped fullerene and metal oxide layers form Ohmic contacts with the wide bandgap and narrow bandgap perovskite sub cells and demonstrate low resistivity and high power conversion efficiencies.
