Abstract

Hybrid metal halide perovskites have shown increasing success as active layers for photovoltaics cells, although concerns about water stability remain a hindrance to widespread commercialization. Two-dimensional, Ruddlesden-Popper phase perovskites, which incorporate larger, more hydrophobic organic cations, have been proposed as an alternative. Although they demonstrate increased water stability, they have increased exciton binding energies and thus decreased charge-carrier mobilities and charge-carrier lifetimes. To fully understand the limits that these properties impose, the interplay between exciton and free charge-carrier formation dynamics is examined.
