摘 要

目前随着全球经济化的发展，资源问题已经是每个国家不得不面对的一个重要问题。在传统能源无法满足需求时，太阳能就成为了一个有效的能源途径，太阳能电池也就随之而兴起。而非晶硅太阳能电池与晶体硅太阳能电池相比具有质量轻、工艺简单、成本低和耗能低等优点，现在备受人们的青睐。

本论文对非晶硅太阳能电池的结构及原理进行了简单的介绍，通过查阅当前较新的研究，对可能优化非晶硅太阳能电池的方面提出假设，期望运用软件进行理论模拟试着找出提高电池转换效率的有效办法，对非晶硅太阳能电池的优化设计提出理论依据。

本文通过比较非晶硅太阳能电池P层掺杂和掺杂浓度变化对电池效率的影响， p层厚度、i层厚度变化对电池开路电压V_OC，短路电流J_SC，填充因子FF和光电转换效率η带来的影响以及禁带宽度对非晶硅太阳能电池的影响。比较总结出非晶硅太阳能电池最优的设计方案和未来的发展方向。

通过理论分析，我们得出以下结论：

1. P层掺杂之后，非晶硅太阳能电池效率更高；
2. P层掺杂浓度为5*10¹⁹cm^-3是最适宜浓度；

3. 当电池P层厚度在18nm时，电池的工作效率取得最高值；

4. 当电池i层厚度在400nm时，电池的工作效率取得最高值；

5. 当电池的禁带宽度为1.7eV时，电池的工作效率取得最高值。

Theoretical simulation of amorphous silicon solar cell performance

Abstract

With the current development of the global economy, the question of resources is an important issue that we have had to face in each country. When unable to meet the needs of traditional energy, solar energy has become an effective way of energy, solar cells and the rise along with it. Amorphous silicon solar cells and crystalline silicon solar cells compared with the light weight, the process is simple, low cost and low power consumption advantages, so many people like it.

In this paper, the structure and principles of amorphous silicon solar cells for a simple introduction, by referring to the current relatively new research on the optimization of amorphous silicon solar cells may put forward assumptions, expectations using software to try to find the theoretical simulation to improve effective way cell conversion efficiency of amorphous silicon solar cell design optimization proposed theory.

Through comparing the impact doping concentration doping P layer and the amorphous silicon solar cell efficiency of the battery, p layer thickness, i layer thickness of the battery open circuit voltage VOC, short-circuit current JSC, fill factor FF, and with the photoelectric conversion efficiency η and to influence on the band gap of the amorphous silicon solar cell. Compare best summed amorphous silicon solar cell design and the future direction of development.

Through theoretical analysis, we conclude that the conclusion:

1. After the P-doped layer, the higher the efficiency of amorphous silicon solar cells;

2. P doping concentration of 5 *10¹⁹cm^-3 is the most suitable concentration;

3. When the thickness of the p-layer 18nm battery, the battery efficiency of the highest value obtained;

4.When the battery i-layer thickness in the 400nm, batteries work has high efficiency;

5. When the band gap of 1.7eV battery, the working efficiency of the battery to obtain the maximum value.

Keywords: Amorphous silicon, solar cell, thickness, doping, Conversion efficiency.
