Abstract
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.
期刊介绍：
Physica Scripta is an international journal for original research in any branch of experimental and theoretical physics. Articles will be considered in any of the following topics, and interdisciplinary topics involving physics are also welcomed:
-Atomic, molecular and optical physics-
Plasma physics-
