Previous work defines the buffer capacity as the reciprocal of the change in an ecosystem state variable (e.g. P concentration of a water body) per unit of forcing applied (e.g. per unit P input) (Jørgensen and Mejer 1977). More recently, buffer capacity was defined as one minus the...
Recent years have seen swift increase in the power conversion efficiency of perovskite solar cells (PSCs). Interface engineering is a promising route for further improving the performance of PSCs. Here we perform first-principles calculations to explore
