太阳能电池中硫化锌缓冲层研究进展

Research progress of zinc sulfide buffer layer in solar cells

  • 摘要: 随着经济的不断发展, 人类对能源的需求日益增长。由于传统化石能源面临着能源枯竭和环境污染等问题, 太阳能作为可再生能源有着很大的发展前景, 其中太阳能电池的研究更是成为研究热点。但制约太阳能电池性能的因素依旧存在, 例如: 界面问题、稳定性问题等。通过在载流子传输层/电极及载流子传输层/光吸收层之间引入能带结构合适的缓冲层, 可有效解决界面间的能带失配、载流子复合、化学反应等问题, 进而提高电池中的电荷分离及收集效率, 使得界面及稳定性问题得到有效改善。本文总结了硫化锌(ZnS)作为不同太阳能电池中的缓冲层的研究成果, 分析了不同方法制备的ZnS的区别以及对电池性能的影响, 并展望了其在太阳能电池的应用前景。

     

    Abstract: With the development of the economy, mankind's demand for energy is increasing. As traditional fossil energy is facing problems such as energy depletion and environmental pollution, solar energy has great development prospects as a renewable energy source, and the research of solar cells has become a research focus. However, the factors that restrict the performance of solar cells still exist, such as interface problems, stability problems, etc. By introducing a buffer layer with a suitable energy band structure between the carrier transport layer/electrode and the carrier transport layer/light absorption layer, it can effectively solve the problem of energy band mismatch between the interface, carrier recombination, chemical reaction, etc. This paper summarized the research results of zinc sulphide (ZnS) as a buffer layer in different solar cells, and analysed different methods to prepared the ZnS. Finally, the difference between ZnS and its impact on battery performance, and its application prospects in solar cells are forecasted.
