太阳能级硅激光刻槽埋栅电池的研究

LASER GROOVED BURIED CONTACT SOLAR CELLS ON SOLAR - GRADE SILICON SUBSTRATES

探讨了廉价太阳能级硅材料对电池性能可能的影响，据此对激光刻槽埋栅电池的工艺加以优化．在此基础上制作的大面积太阳电池的转换效率达到１６．５９％．

Solar- grade silicon substrated contain more oxygen, carbon and metal impuritiesthen semiconductor-grade, expedally FZ silicon. On the basis of the knoWledge about theoxygen behavior in various high temperature processes, improved conditions are carried out toenhance cell's performance. The Cell with 16.59% conversiton effidency has for obtained.
