美国麻省理工学院林肯研究所采用激光技术制作硅太阳电池的pn结取得成功。这种方法只须一次操作即可完成,而且装置简单,易于实现操作的连续自动化,故适合于制作硅带状结晶的太阳电池。 Massachusetts Institute of Technology Lincoln Institute using laser technology to make pn junction silicon solar cell was successful. This method can be completed only one operation, and the device is simple and easy to achieve continuous operation automation, it is suitable for the production of silicon ribbon solar cells.
