Design of B,N Co‐Doped Carbon Spheres for Highly Effective Back Interface Engineering in Planar Carbon‐Based Perovskite Solar Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The energy level mismatch of the perovskite/carbon back interface is decreased remarkably by using B, N co‐doped carbon sphere electrode in C‐PSCs, leading to effective charge carrier separation, extraction, and transport at the back interface. Combined with further buried modification using AMPA, the power conversion efficiency of the C‐PSCs is up to ...
