文档介绍：太阳能电池片制造工艺及铝背场钝化工艺的研究
摘要
随着社会的发展,人类对能源的需求变得多样化,由于原始能源的获取主要通过煤、石油、天然气等石化能源,但是这些能源变得越来越少,同时还会造成环境的污染。近年来随着人们对环境的重视,对新能源的需求变得越来大。因此光伏行业受到的极大重视,在短短的几年里便得到迅速发展,我国光伏行业以每年30%左右的增速发展。作为一个新兴的行业,有很多人对太阳能电池的生产还不了解。
本文的亮点是:1)系统的介绍了太阳能电池片的制造工艺,从制绒工艺到最后的印刷烧结和检测,为以后深入学习打下基础。2)对比验证了商业常用的两种网版(250、280)和两种浆料的优缺点及对一些常见问的分析,并得出在现有的商业烧结条件下的最好搭配,并对现实中的电池片生产提供了参考。

Solar Sell Processing and Investagation of Al-BSF Passivation Quality
ABSTRACT
With the development of society, human demand for energy to diversify. As the primary energy, mainly through the acquisition of coal oil,gas,and other fossil fuels. But these energy sources e less and less. At the same time also cause environmental pollution. In recent years,as people focus on the demand for new energy sources have e increasingly large. Therefore, great attention by the PV industry. In just a few years, it has developed rapidly. China’s PV industry annual growth rate of about 30% of the development. As an emerging industry. Many people do not understand the production of solar cells.
The highlight of this article. 1) A systematic introduction to manufacturing processes for solar cells. From the system down to the final printing process and test fired. Lay the foundation for future in-depth study. 2) Comparative validation of mercial version of work() and draw on existing business with the best sintering conditions. The cells and production of reality to provide a reference.
KEY WORDS: solar cell, processing, Al-BSF, surface bination, screen-printing technology
