Chiral-structured heterointerfaces enable durable perovskite solar cells

Abstract

An electronic device including: an electron-transport layer; a chiral interface layer disposed on a surface of the electron-transport layer, wherein the chiral interface layer includes a chiral compound, wherein the chiral compound is substantially enantiomerically pure or racemic; and a perovskite layer disposed on a surface of the chiral interface layer; or an electron-transport layer, wherein the electron-transport layer further includes a chiral compound, wherein the chiral compound is substantially enantiomerically pure or racemic; and a perovskite layer disposed on a surface of the electron-transport layer. The electrical device exhibits improved mechanical failure and chemical degradation relative to electrical devices not including the chiral interface layer or the electron-transport layer further including the chiral compound.
