A dual function-enabled novel zwitterion to stabilize a Pb–I framework and passivate defects for highly efficient inverted planar perovskite solar cells

Author affiliations

Abstract

A novel zwitterion named bethanechol chloride (BTCC) was introduced to simultaneously stabilize a Pb–I framework and passivate defects for efficient inverted perovskite solar cells. The BTCC-assisted device yielded an elevated power conversion efficiency of 20.45% with an open-circuit voltage of 1.14 V.
