Inside Cover: Molecular Ferroelectrics‐Driven High‐Performance Perovskite Solar Cells (Angew. Chem. Int. Ed. 45/2020)

This is the authors' abstract. We don't add key points for this paper.

A homochiral molecular ferroelectric was incorporated into a perovskite film to enlarge the built-in electric field of the perovskite solar cell, thereby facilitating charge separation and transportation for improved device performance. In their Research Article on page 19974, J. Zhao, W.-Q. Liao, G.-F. Zou, and co-workers show that the molecular ferroelectric component of the perovskite solar cell passivates the defects in the perovskite active layers, reducing nonradiative recombination.
