Title:
Mesoporous Electron Selective Contacts Enhance the Tolerance to Interfacial Ions Accumulation in Perovskite Solar Cells 
Abstract:
Perovskite-based solar cells are emerging as a potential new leading photovoltaic technology. However, several fundamental aspects of the stability remain unclear. In this paper, we combine experimental measurements and numerical simulations to show that a mesoporous interface between the perovskite and the electron collection layer mitigates the reversible performance loss associated with the ion migration. We argue that larger interfacial area dilutes the concentration of defects that accumula...    »
