Abstract

We report a facile mechanochemical route for the stabilization of a structurally stable α-FAPbI₃ perovskite by fine and controllable stoichiometry modification in mixed-cation (MA)_x(FA)_1−xPbI₃ perovskites. Moreover, the mechanoperovskite with a composition of (MA)_0.25(FA)_0.75PbI₃ was used for solar cell fabrication showing a power conversion efficiency (PCE) of 14.98% with a high short circuit current (J_SC) density at 23.7 mA cm⁻².
