太阳能电池片制造工艺及铝背场钝化工艺的研究 摘 要 关键词：，，，，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 become less and less. At the same time also cause environmental pollution. In recent years,as people focus on the environment.The demand for new energy sources have become 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 the commercial version of two common network(250.280count) and draw on existing business with the best sintering conditions. The cells and production of reality to provide a reference.
