The utilization of low-dimensional perovskites (LDPs) as interlayers on three-dimensional (3D) perovskites has been regarded as an efficient strategy to enhance the performance of perovskite solar cells. Yet, the formation mechanism of LDPs and their impacts on the device performance remain elusive.
Non-ideal charge selective layers for wide bandgap perovskite solar cells lead to high voltage loss.

Highly efficient perovskite solar cells (PSCs) in the n-i-p structure have demonstrated limited operational lifetimes, primarily due to the layer-to-layer ion diffusion in the perovskite/doped hole-transport layer (HTL) heterojunction, leading to conductivity drop in HTL and component loss in perovskite.
We believe that incorporating a polymeric charge-selective interlayer is a promising strategy to enhance the operational lifetime of perovskite solar cells and solar modules, paving the way for their commercial application. Tin (II) chloride dihydrate (SnCl 2 ·2H 2 O, 99.99%) was purchased from Aladdin.
Inverted perovskite solar cells (PSCs) have attracted broad research and industrial interest owing to their suppressed hysteresis, cost-effectiveness, and easy-fabrication.
