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.

等离子体辅助二维石墨烯太阳能电池的建模与仿真

石墨烯是一种重要的光能转换光伏材料，主要是由于其令人兴奋的特性，包括更高的载流子迁移率。通过用石墨烯层代替“空穴传输层”（HTL），钙钛矿太阳能电池的效率可以得到提高。本研究展示了使用等离子体增强化学气相沉积（PECVD）技术生长石墨烯如何影响器件效率。我们使用SCAPS-1D建立并模拟了ITO/PCBM/CsPbI3/石墨烯的模型，并使用CsPbI3作为吸收剂，PCBM作为电子传输层（ETL），石墨烯作为HTL。发现太阳能电池效率与等离子体参数之间存在数值相关性，并将模拟模型的效率与数值计算的效率进行了比较。此外，研究发现，增加石墨烯片的电子和离子密度会导致器件效率下降，这是由于与德拜长度成反比关系，而增加电子和离子温度会导致器件效率增加，这是由于与德拜长度成线性关系。这表明，在理想的吸收层和HTL厚度下调整各种等离子体参数，可以提高器件的效率，改善器件的性能和实际应用。所得到的结果已经从先前的基于太阳能电池的研究中得到了验证。

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.
