摘要

甲基铵三碘化铅（CH3NH3PbI3）是一种金属卤化物类包晶石，由于其显著的光电特性，特别是在包晶石太阳能电池（PSC）和包晶石发光器件（PLED）中的应用而备受关注。本文研究了碳电极层数对无空穴传输材料（HTM-free）玻璃/FTO/c-TiO2/m-TiO2/m-ZrO2/碳单片 PSCs 的光伏参数和阻抗谱的影响。结果表明，碳电极层对填充因子和串联电阻有重大影响。当在 PSC 中使用三层碳电子时，可观察到最佳的填充因子和串联电阻值。这是由于较高的电荷传输、较高的导电性、较高的电子迁移率和较低的重组损耗。

Impact of carbon electrode layer on the series resistance and fill factor of CH3NH3PbI3 perovskite solar cell

Methylammonium lead triiodide (CH3NH3PbI3) is a metal halide perovskite that is attracting great attention owing to its remarkable optoelectronic properties especially in perovskite solar cells (PSCs) and perovskite light-emitting devices (PLEDs). In this work, the impact of the number of carbon electrode layers on the photovoltaic parameters and impedance spectra of hole transport material-free (HTM-free) glass/FTO/c-TiO2/m-TiO2/m-ZrO2/carbon monolithic PSCs is examined. A significant influence of the carbon electrode layers on the fill factor and series resistance is revealed. The optimum values of fill factor and series resistance are observed when a 3-layered carbon electron is used in the PSC. This is due to higher charge transportation, higher electrical conductivity, higher electron mobility, and lower recombination losses.
