基于丝网印刷的N型硅基太阳能电池的研制

The Fabrication of N Type Silicon Solar Cells Based on the Screen Printing

传统制备P型硅基太阳能电池的方法被应用到N型硅片上,成功制备出n+np+结构的N型硅基太阳能电池。在制备过程中利用补偿法形成np+背结,无需保护背面。最高效率为13.1%(Voc=0.58V,Jsc=31.2mA/cm2,FF=72.4%)。

N type silicon based solar cells of n＋np＋ structure have been successfully prepared using the traditional method of preparing P type silicon solar cell. In the preparation process, the np＋ back junction is formed without protecting back side using compensation method. The highest efficiency of the solar cell is 13. 1%（Voc=0. 58 V,Jsc=31.2 mA/cm2 ,FF=72.4%）.
