Abstract

Abstract : Highly efficient P‐I‐N type perovskite/bulk‐heterojunction (BHJ) integrated solar cells (ISCs) with enhanced fill factor (FF) (≈80%) and high near‐infrared harvesting (>30%) are demonstrated by optimizing the BHJ morphology with a novel n‐type polymer, N2200, and a new solvent‐processing additive. This work proves the feasibility of highly efficient ISCs with panchromatic absorption as a new photovoltaic architecture and provides important design rules for optimizing ISCs.
