Abstract

This work investigated a method for improving the efficiency of solar cells through the incorporation of carbon nanotubes (CNTs), which were used as the absorber layer of the solar cell. The CNTs were generated using plasma-enhanced chemical vapor deposition (PECVD). The use of the PECVD-generated CNTs in the absorber layer of the solar cell was found to increase the electrical conductivity due to the introduction of a large number of free charge carriers in the form of electrons and holes. We were thus able for the first time to estimate a relation between plasma variables and the efficiency of the proposed solar cell. The results showed that an increase in electron and ion density resulted in an increase in the efficiency of the solar cell, whereas an increase in electron and ion temperature led to a decrease in efficiency. We also studied the variation in efficiency in relation to the absorber layer of the proposed solar cell structure. The results obtained were consistent with those from previous studies based on solar cells.

等离子体辅助碳纳米管在太阳能电池中的应用

这项工作研究了一种通过加入碳纳米管（CNT）提高太阳能电池效率的方法，碳纳米管被用作太阳能电池的吸收层。碳纳米管是通过等离子体增强化学气相沉积（PECVD）生成的。由于引入了大量电子和空穴形式的自由电荷载流子，在太阳能电池吸收层中使用 PECVD 生成的 CNT 可提高导电性。因此，我们首次估算出了等离子体变量与拟议太阳能电池效率之间的关系。结果表明，电子和离子密度的增加导致太阳能电池效率的提高，而电子和离子温度的增加则导致效率的降低。我们还研究了效率的变化与拟议太阳能电池结构的吸收层的关系。所获得的结果与之前基于太阳能电池的研究结果一致。

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.
