Abstract

A significant photovoltaic material for greater light energy conversion is graphene, mostly due to its exciting features including greater carrier mobility. By substituting a graphene layer for the "hole transport layer" (HTL), a perovskite solar cell's efficiency can be increased. This study demonstrates how growing graphene using the plasma-enhanced chemical vapor deposition (PECVD) technique affects the device efficiency. We use SCAPS-1D to build and simulate a model of ITO/PCBM/CsPbI₃/graphene and use CsPbI₃ as absorber, PCBM as the electron transport layer (ETL) and graphene as the HTL. The efficiency of solar cell and the plasma parameters are found to be numerically related, and the efficiency of the simulated model and the numerically computed efficiency are compared. Furthermore, it is discovered that increasing the electron and ion density of the graphene sheet causes the device's efficiency to decrease due to an inverse relationship with the Debye length, whereas increasing the electron and ion temperatures causes the device's efficiency to increase due to a linear relationship with the Debye length. This indicates that by adjusting the various plasma parameters at an ideal absorber layer and HTL thickness, the device's efficiency can be increased, improving its performance and practical applications. The obtained results have been verified from the previously done researches based on solar cells.

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
