摘　　要：采用轻掺杂、浅结工艺,将发射极方块电阻控制在60Ω/□,基于国产生产线的常规工艺,获得了平均效率为17.8%的商业化Cz-Si太阳电池。如果将发射极方块电阻控制在80Ω/□,结合密栅和新型浆料,产业化电池的平均效率可达18%。Shallow emitters （60Ω/□） with a low doping concentration were adopted, and the sheet resistance is controlled to be 60Ω/□. Cz-Si solar cells are fabricated in the domestic production-line with regular process, and the average efficiency is found to be 17.8%. If the sheet resistance of the shallow emitters is increased to be 80Ω/□ and new sliver paste and tight-grid pattern are adopted, an average efficiency of 18% can be obtained.
