新兴激光加工技术制作太阳能电池, 可极大地避免太阳能电池制造过程中的损害, 是提高太阳能电池转换效率, 降低制作成本的有效手段之一。目前许多太阳能电池终端用户使用激光加工技术已有一段时间, 这表明了激光加工技术在光伏行业应用的可行性。阐述了国内和国际上对激光技术在光伏产业中应用的最新动态, 重点论述了激光切割技术、非接触加工技术、激光刻蚀技术、激光划刻技术、激光钻孔技术以及这些技术在光伏产业中应用的优缺点。在此基础上进一步指出目前虽然激光加工应用于太阳能电池制作技术的研究还不够充分, 如何进一步克服激光切割技术、非接触加工技术、激光刻蚀技术、激光划刻蚀技术、激光钻孔技术等在太阳能电池制作过程中遇到的问题还没有相应措施, 但进一步扩大激光加工在光伏行业的应用技术将是太阳能电池制作和发展的一个重大趋势, 必将成为一个新的研究重点, 也仍将是国内和国际研究的热点问题。

It is a effective measure to improve the solar cells conversion efficiency and reduce the manufacture cost. At present, there is a long time since laser process technology has been used by solar cell manufacturer, this indicates that it is feasible to use laser process technology for photovoltaic industry. In this paper, the new trends of laser process technologies used for photovoltaic industry are stated, especially, laser cutting, non-contact process technology, laser etching, laser sweeping, laser drilling. Based on above mentioned, the research on laser technology in photovoltaic industry is not enough sufficient. There has little means to overcome the encounter problem, but it will become a new research, even to inland or international.
