摘要:
Methods of fabricating solar cells using a metal-containing thermal and diffusion barrier layer in foil-based metallization approaches, and the resulting solar cells, are described. For example, a method of fabricating a solar cell includes forming a plurality of semiconductor regions in or above a substrate. The method also includes forming a metal-containing thermal and diffusion barrier layer above the plurality of semiconductor regions. The method also includes forming a metal seed layer on the metal-containing thermal and diffusion barrier layer. The method also includes forming a metal conductor layer on the metal seed layer. The method also includes laser welding the metal conductor layer to the metal seed layer. The metal-containing thermal and diffusion barrier layer protects the plurality of semiconductor regions during the laser welding.
摘要(中):
描述了在基于箔的金属化方法中使用含金属的热阻挡层和扩散阻挡层来制造太阳能电池的方法,以及所得的太阳能电池。 例如,制造太阳能电池的方法包括在衬底中或上方形成多个半导体区域。 该方法还包括在多个半导体区域上方形成含金属的热阻挡层和扩散阻挡层。 该方法还包括在含金属的热和扩散阻挡层上形成金属种子层。 该方法还包括在金属种子层上形成金属导体层。 该方法还包括将金属导体层激光焊接到金属种子层。 含金属的热扩散阻挡层在激光焊接期间保护多个半导体区域。 p>
