摘要

凭借出色的光热稳定性，无机钙钛矿太阳电池（Inorganic perovskite solar cells

IPSCs）已成为研究焦点，但界面缺陷富集与载流子不利堆积仍严重掣肘其光伏指标。本研究在钙钛矿吸收层与电子传输层之间插入1

3-丙二胺氢碘酸盐（1

3-Propanediamine Dihydroiodide，PDADI）对钙钛矿表面施行界面调控。实验结果显示，PDADI可显著降低缺陷态密度，加速界面电子抽取与输运，进而抑制非辐射复合。最终，经PDADI修饰、全空气环境制备的反式IPSCs开路电压平均提高约120 mV，光电转换效率（Power conversion efficiency，

PCE

）达到19.50%。

Abstract

Inorganic perovskite solar cells (IPSCs) have become the focus of research due to their excellent photothermal stability

but the enrichment of interface defects and the unfavorable accumulation of carriers still seriously restrict their photovoltaic performance. In this study

3-Propanediamine Dihydroiodide (PDADI) was inserted between the perovskite absorption layer and the electron transport layer to regulate the interface of the perovskite surface. The experimental results show that PDADI can significantly reduce the density of defect states

accelerate the extraction and transport of interface electrons

and thus inhibit non-radiative recombination. Finally

the open circuit voltage of the IPSCs modified by PDADI and fabricated in fully ambient-air conditions increased by about 120 mV

and the power conversion efficiency (

PCE

) reached to 19.50 %.
