用AMPS-1D模拟CdS/CIGS串联多结太阳电池的效率
Simulation of the Efficiency of CdS/CIGS Tandem Multi-Junction Solar Cells Using AMPS-1D
摘要：
在本文中，我们进行CdS/CIGS太阳能电池的数值模拟，通过使用AMPS-1D软件，旨在制定新的多结叠层太阳能电池提供其最有效的操作的优化设计。我们从单结CdS/CIGS太阳电池的数值模拟开始，计算结果表明，当CIGS p层厚度为200 nm时，电池的效率最高可达17.3%。这一结果与实验数据非常一致，其中太阳能电池厚度为1微米时，最高效率为17.1%。利用单结太阳电池的数值模拟结果，我们开展了新的多结串联CdS/CIGS太阳电池结构的设计和优化。数值模拟结果表明，在AM1.5标准照度下，CIGS p层厚度为600 nm时，该太阳能电池的最大效率为48.3%.
英文摘要：
In this paper we conduct numerical simulation of CdS/CIGS solar cells by use of the AMPS-1D software aiming to formulate the optimal design of the new multi-junction tandem solar cell providing its most efficient operation. We start with the numerical simulation of single-junction CdS/CIGS solar cells, which shows that its highest efficiency of 17.3% could be achieved by the thickness of CIGS p-layer of 200 nm. This result is in a good agreement with experimental data where the highest efficiency was 17.1% with the solar cell thickness of 1 micron. By use of the results of the numerical simulation of the single-junction solar cells we developed the design and conducted optimization of the new multi-junction tandem CdS/CIGS solar cell structure. Numerical simulation shows that the maximum efficiency of this solar cell is equal to 48.3%, which could be obtained with the thickness of the CIGS p-layer of 600 nm at a standard illumination of AM 1.5.
