Small molecule interfacial cross-linker for highly efficient two-dimensional perovskite solar cells
文献摘要：
The nonradiative recombination of charge carriers at the hole transport layer(HTL)/perovskite interface generally induces remarkable performance loss of the inverted two-dimensional perovskite solar cells(2D PSCs).Herein,a cross-linkable small molecule of 2-mercaptoimidazole(2-MI)was introduced into the nickel oxide(NiOx)/2D perovskite interface.Experiments have confirmed the formation of Ni-N cova-lent bond by N atom in the 2-MI and Ni in the NiOx and the coordinating between S atom of 2-MI and under-coordinated Pb2+near to the NiOx/perovskite interface,which contributes to creating a cross-linking between NiOx/perovskite interface to restrain charge carrier recombination and enhance the extraction of hole carriers at the interface.Besides,the 2-MI modification layer is also beneficial for pro-moting the crystallinity of 2D perovskite.Consequently,the inverted 2D PSCs with 2-MI modification achieved the best power conversion efficiency of 15％.This paves a route to acquire highly efficient 2D PSCs by constructing a cross-linking at the NiOx HTL/2D perovskite interface.
