摘      要：In the perovskite photovoltaic community, sandwiched device configurations such as n-type transport layer-perovskite-p-type transport layer (n-i-p, regular) or p-i-n (inverted) are research mainstreams for higher power conversion efficiencies (PCEs)[1].One of the important functions of these transport layers (TLs) is the construction of built-in-electric fields (BFs) for carrier directional diffusion [2].
